Some people always ask me how to learn a lot of technologies and wonder how to become the so-called Great God.
In fact, this article is based on some of my experiences and tells you how to learn technology, rather than how to become a great god. There is no such thing as success, only smart thinking, down-to-earth practice, and an increasingly closer ideal, as well as opportunities and luck.. The reason for using this title is nothing more than attracting more people, especially many people who have unrealistic fantasies about becoming a great god. I hope readers can get something from it without wasting their time reading this article. This article is just my opinion. It is not a truth. Please do not believe in it without thinking about it.
1. Mainstream values
Value is a mysterious word. When I was a freshman three years ago, I had no idea about this word, but now I understand it slowly. A value is a person's evaluation of the value of various things. Some people think that money is the most important thing. Most people do not agree to it if they pursue money all their lives. Some people think that happiness is the most important thing, but there are various puzzles. No one is right or wrong about the value itself. However, we will still evaluate a person's quality, and our evaluation is based on mainstream values. Mainstream values hold that people should do what they are doing to their own interests in society, at least to others, which is indeed worthy of approval. Mainstream values also often think that people should make a difference, while many people even think that everyone should have lofty ideals and aspirations. Many parents think that going to college is the most important thing, I don't even have a face when I can't get into college. I don't agree with this. I think the most important thing is Do what you want to do that is harmless to others. If it happens to be what society needs, it would be better. If not, there is nothing wrong with it..
2. Social Needs
Some students love to play games, and they have made great efforts to play games. They have spent a lot of energy, learned various skills, and even paid for equipment and equipment. Many people will think that such a person's practice is wrong, a typical corruption symbol. Some people are very focused on learning technical knowledge, and finally become the master of the school brother and sister.
It is also a waste of food, it is also a focus on the serious, why the gap is so big. The reason is very simple. People who have graduated to play games often cannot save research, go abroad, or find a good job, but they can take off from various companies. The difference here lies in social needs.In today's Internet society, many software and hardware engineers are required. In fact, some internet companies also need professional players to perform game tests, but the number of players is small, so it is difficult for gamers to become professional players.
In the same sense, there are many people who like playing and singing, but it is difficult for them to develop their hobbies at home, because there is no need for so many professional players and singers in society, as a result, they are likely to fail and face the dilemma of graduation, unemployment, and lack of work.
3. Create Talents in the environment
There is a saying that "the family of the poor is talented". I used to believe this sentence, but I slowly did not believe it. In China, the level of scientific research is not as good as that of foreign countries. It is clear that Chinese people are more stupid than foreigners. Besides, there are many Chinese people, and there are always people smarter than Einstein. Of course, there are many factors, of which the economic factors are more important. It is often said in the news that the country needs to increase investment in scientific research funds, indicating that increasing funds is usually beneficial to the development of scientific research.
A poor man who loves mathematics is willing to eat and save money to buy books. Later, he became a famous mathematician. This is the evidence of the most classic family talents of the poor. But imagine, if this person is poorer, not enough to eat every day, ELE. Me Dizzy, can he still be a mathematician? Try again, this family is rich and has a status. since childhood, they have access to various books and even have the opportunity to communicate with specified mathematicians. This person is likely to become a more famous mathematician.
Some people may say that my analysis is extreme. The family of the poor can generate mathematicians, which is acceptable and true. But will the poor have talented hardware engineers? I think it is very difficult. The learning conditions for mathematics are very simple. If you have some books, you can learn them very deeply, but the learning conditions for some things are much higher. A person who is very poor at home from an early age has no chance to access the computer (of course not necessarily poor, or may worry about affecting learning at home ), Even if he is a potential talented programmer, he has no chance to study.In this way, when he starts to have a chance, he is at least missing a lot compared to a person with better conditions. Of course, he has the opportunity to learn at a faster speed. He is already a lucky person.
The environment creates talents, which is also related to the above social needs. Because social needs directly affect your learning environment, many people who love music and other knowledge do not have a good development opportunity.
In an environment like a university, apart from courses, there is also a great treasure, that is, various learning resources. We can access Various excellent students, You do not have to spend money LibraryI borrowed a variety of books and spent a lot of money on the library in xidian. Wanfang DatabaseAnd other free use rights for students to learn and use, and various competitions and other activities provide FundingAnd LabAnd provides us with rare learning conditions.
Taking my electric competition as an example, during the electric competition, I came into contact with a variety of instruments, many of which were very expensive, such as analyzer and network analyzer (said to be the "treasure of the Town Court" of the General Hospital ", other schools do not), and many expensive devices are also used. Ordinary resistance seems very cheap as long as a fraction of the money, but the accuracy of one thousandth of the 0.01 euro resistance, a need for more than a dozen; a common Op Amplifier, a just a few cents, however, some chips used during the electric competition, such as high-gain and high-precision op-ops, require 50 chips. One chip is a attenuation consisting of three precision resistors. The working frequency is limited to 6 GHz, a small device requires hundreds of thousands. A high-frequency circuit that is not complex may cost thousands of dollars. Generally, it is difficult for students to bear such high fees. These rare learning resources can be obtained when you have the opportunity to participate in the competition.. It also shows that the threshold for dedicated hardware is relatively high.
4. Invest for yourself
I usually spend money to buy something to learn. During my college career, I spent thousands of dollars on books and learning equipment (mainly hardware devices). Many people were surprised to hear that I thought I was Gao fushuai. In fact, I just want to say that I am a student from a student's bank. But my money is not white, and I learned a lot. After graduation, I found a satisfactory job, And I could recover the cost in less than a month. Such high ROII am afraid that any form of entrepreneurship is beyond the reach of any other means.
The poor always want to save money, while smart people prefer to borrow money to invest and then have the opportunity to become rich. However, investing in yourself will not be wrong in any case.
5. Learn to choose
It is needless to say that you have learned how to choose from this point. Everyone knows the saying "I picked up sesame seeds and lost watermelon." If Nothing will happen if you don't know how to make a choice.. Some people want everything and do everything well, and often do nothing well in the end.
6. risks and returns
When I was a senior, I decided not to study for the moment. Many people advise me to study, some of whom feel that I am doing well and I have the opportunity to seek insurance research. Some also feel that I can first obtain a quota for insurance research and then find a job, if you haven't found a solution, you can leave a path for yourself. However, I have a clear idea. After my junior year and next semester, I have never thought about going to research, and I have spent a lot of energy explaining my thoughts with my family. I have to say that it is risky to do so. Some time ago I was worried, and even began to doubt or regret it for a few moments. Is it true that I did too much, in case you cannot find a satisfactory job, it is really difficult. However, I was lucky and had a good character. I found a satisfactory job. I believe that after three years, my situation will be better than that of my new graduate.
We all know that real estate is very profitable, but high returns are often accompanied by high risks. I also mentioned how to make choices, Whether you are willing to take risks, whether you can have an accurate grasp of yourself and things, whether you dare to take the consequences of the risks, and ultimately everyone's choice is different.
7. Power
To do something difficult, you often need motivation. There are two motivations: reward and punishment.. If a student with a good score can receive a scholarship, the reward will be applied. If a student who has not passed the examination fails to take the exam again, the punishment will apply. Interest is an important motivation for reward, because it can be satisfied. Obviously, we all hope to be motivated by incentives rather than punishments.
8. Interest
For me, the most important reason is that I am very interested in learning technology. Interest is the best teacherIf you are interested in learning, you can get the source of endless motivation.
9. self-motivated
Self-motivated is also an important motivation, A person with no ambition does not exist, but his or her ambition is different.. People with strong self-motivation are easy to compete for a strong victory. Winning a strong victory cannot be simply evaluated as a shortcoming. If you use it properly, it can provide you with tremendous power, it is the biggest advantage of being a good person.
10. Sense of presence
The most basic physiological need of a person is to live, or to exist. The most basic psychological requirement is the sense of presence.. People often do things in order to prove themselves, and their abilities are affirmed and praised by others. They must be full of Sense of presence. A sense of presence is the source of lasting motivation for a person.
11. focus and work hard
Every successful person has a common feature, that is, earnest and hard work. The same is true for the great gods. I just want to remind some students that they should not keep up with it. Opportunistic fantasy.
12. Wisdom of inquiry
There will always be something we don't know, and someone around us knows it very well. At this time, some people started to ask questions without thinking about them. I have answered many technical questions.
The biggest obstacle to a question is that the question cannot be clearly described.. If you ask a doctor, what should you do if you are not feeling well? The doctor will ask you questions, such as what you eat, and then give you temperature measurement and so on, and gradually judge the problem. But do not forget that it is the doctor's duty to solve the patient's problem, and you usually pay for it at the end. When you ask people around you questions online or through other channels, you should understand that the help provided by others is free of charge. Especially the great gods will be very busy. The time of others may be more precious than your time. When you ask other people's questions, you can't describe them in a few words. Why do others ask questions as patiently as doctors, what can I do for you?
People are often seen Ask some simple questionsWhat are the Color Ring Resistance, how to identify the three feet of the transistor, for freshman students, I can fully understand. However, if you continue to ask this question a long time later, I am afraid it will not be good. Everyone should know about Baidu encyclopedia, search for the color ring resistance, and then you will be able to come up with a detailed graphic explanation, which is much easier to understand and authoritative than others who use words to answer questions.
Some people may say that I know many very enthusiastic people who take special care of me and have a good relationship. I can always ask. First of all, it is clear that if all your knowledge is told by others, you will never be better than people who tell you this knowledge. Secondly, for some simple knowledge, someone else can tell you, but what about a complicated problem? Even if that person would like to help you, but this question is too deep and I cannot tell you a few words. What are you going to do at this time? I won't say much about it.
Some people ask for advice, It's like someone else is obligated to help him.. I won't say thank you. It may be that your character is too restrained and relatively better, but you should learn this. Some people are still impatient and eager to ask other people's questions, have a strong tone, and suspect that others are not answering well. I just want to say that this kind of person is still rarely provoked.
There is also a common question that makes respondents dislike. Some people seriously spent a long time doing something, such as a complicated circuit or a long program, and then found that they didn't work. Check if the problem persists. Copy all the code and send it to others., And then the performance is extremely poor, kneeling for the help of the great god. I am hard to criticize such people. Many of them are very serious.
The questioner often thinks that, for the great gods, isn't this code able to see problems at a glance? But what I want to say is, This kind of fault check problem is often more difficult than writing programs and making circuits. It is easier for me to give you something with the same function.. Especially Circuit, in many cases, it is not just a chat on the Internet that can solve the problem happily.. If everything is so simple, society will not be like this.
What should I do if this problem occurs? I think it should be Independent Problem Solving. As for how to solve the problem, this is a complicated topic, and it also tests IQ, Good exercise opportunities. Most of the time I solve a problem, I don't necessarily think of it right away. Maybe I suddenly got inspiration when I went to bed, and then I wanted to understand it. Maybe I had to look at the information on the Internet and suddenly understood it. There are even examples of problems, such as the discovery of benzene rings in the history of chemistry. The most common and effective method for solving program and circuit faults is implementation by module and inspection by module.. A large system is divided into small modules. Each module is much simpler and implements and checks Each module separately. Each module has no problems, the entire system is basically okay.

This is not to say that you should not ask questions to others. There are two kinds of technical questions to discuss. One is purely a question and a question, and the other is a joint discussion. The latter will promote the progress of both parties and deserves encouragement. The former, the questioner should Have mastered the methods for asking questions, and express your gratitude in a timely manner..

13. Self-learning
Autonomous Learning is something that has been emphasized a long time ago. Human nature is full of curiosity, eager to understand an unknown thing. As far as human society is concerned, it has been exploring the universe since ancient times. This is a manifestation of curiosity. If we regard all mankind as a whole, the ultimate goal of mankind may be to find the truth of the universe, find endless knowledge to satisfy the endless curiosity of mankind. Driven by curiosity, a person should take the initiative to learn. However, for various reasons, especially since childhood in China, many people have lost their desire for knowledge. When we arrive at the university, we do not have the constraints of middle school. Although the university environment is far from as beautiful as we think, we can at least spare a lot of extra-curricular time. Learning what you are interested in requires Autonomous Learning Ability.
There are two most important things for a person: learning ability and thinking style.This is my opinion, and when I was reading a book, I accidentally found that the idea of a netizen on zhihu was surprisingly consistent. I can learn many things during my college career and ensure my basic academic performance, thanks to my learning ability. It took a few days before the examination to read books and brush questions, and the examination passed. What are the important and unimportant courses? My answer is: very important. However, the course knowledge is not equivalent to the exam-based skills. I admit that I lack a lot of theoretical knowledge, especially in mathematics. Although in the short term, I do not have high requirements on the engineering aspects of my work, however, this knowledge is helpful for me to understand many issues and I will make up for it if I have the opportunity.
Some people like to watch video tutorials, I do not recommend watching video tutorials. Video tutorials are often difficult to grasp, and many video tutorials are not formal. Another key point is that most of the video tutorials are made by a third party, rather than official learning materials. You may need to study some of the latest technologies. At this time, the only reference is the official materials, and you cannot find the video tutorial. Video tutorials are also a very basic entry-level technology. A deeper technology often does not provide video tutorials. The importance of English is also emphasized here. Many official documents about Chip manuals are only available in English, It is necessary to adapt to English documents.. You may think that the English documents are difficult to understand. In fact, the technical English documents are well understood in addition to professional words. Professional words can be translated using dictionaries. The reason why I don't understand it is not a problem in English, but because I don't know the professional words. People who have never learned electricity do not understand voltage and tell him voltage. I think, after studying English for so many years, I am not willing to take the CET4 or cet6 exam?
The wisdom of the questions mentioned above has already pointed out that, A lot of questions should be solved independently as much as possible, so that you can exercise your learning ability only when you think twice.. There is a saying that the introverted person is more likely to succeed. From the perspective of learning ability, the introverted person is more inclined to solve the problem on his own, so the learning ability is more exercised, make it easier to succeed.
14. Confidence
Confidence is a profound problem. The essence of confidence can be understood as an estimate of whether a person can handle one thing well before handling one thing. It is very difficult to accurately estimate the difficulty of the problem and your ability in that aspect. In terms of their abilities, many people cannot believe in their potential, and some others are overly confident. People always overestimate or underestimate the difficulty of an issue. In terms of technology learning, I have met two typical people, one of which is a serious lack of self-confidence. What should I do if I say I don't know what to do; another kind of person is over-confident, with a high eye and a low eye. He thinks everything is simple and does not do anything well when he does it himself.
Correct Estimation of your own capabilities is influenced by one's own experience. How can we estimate the difficulty of a task correctly? In fact, the idea is very simple. We only need to conduct some basic research on this matter to greatly improve the accuracy.. The story of the pony crossing the river everyone knows that the pony asked so many people about the depth of the river, but they came up with different answers. Only when I tried it can I know that the river is neither deep nor light for him. Some people spend a few days on the Internet asking others about Android development. It is not difficult, but they did not think about finding an entry-level tutorial to solve Android development. I have already gotten started with the estimation over the past few days, so it's hard to judge a rough idea.
As the saying goes, "Modesty makes people progress" is a simple sentence, but it is quite profound. Is it really so simple, modesty makes people progress, Pride makes people fall behind? What is the principle? Proud people are obviously over-confident and modest people? Here are a few words: inferiority, modesty, pride, self-confidence, and arrogance. These words can be considered to reflect a person's different self-confidence. We may dislike a person who has no skills but is arrogant. However, heroes in American blockbusters are very capable and arrogant. what we feel is domineering, full of positive energy. People have different confidence in different aspects. A person can be both confident and inferior. People who do things well tend to be at your own risk, but they can grasp their confidence in the key points and treat the problem correctly. So self-confidence is often not a simple derogatory term, and sometimes it is a good way to improve self-confidence.Linus, the founder of the open-source operating system Linux, has a classic famous saying: My name is Linus, and I am your god. This sentence is rather arrogant, but Linus's contribution to society is indeed huge. The Android system we use, countless servers that provide various network services for us, are running Linux-based operating systems.
When I took part in the electric competition last year to prepare for the test, I realized that most of my students were junior students and I was a sophomore. I had a lot of courses, especially when I heard about it. However, I did not give up directly because I lost my confidence, nor did I have no preparation because I was excited. Instead, I made serious preparations and finally achieved good results, the selection was successful. In this process, it was not difficult for me to ask others about the electric competition without any significance. Instead, I went online to find previous questions, read books, and made many notes, I also made several sets of final questions on the e-model and carefully prepared the questions (when I took the most serious course in my four-year college study). I knew myself and the problems I was facing more accurately.
In general, it is necessary to grasp the problem accurately, learn more about the problem, and make more preparations, instead of wasting time talking about everything.
15. meaning of life
The significance of life is really a very high philosophical question.
There is a famous mathematician called boolean. One of his major achievements is the invention of Boolean algebra. However, in those days, Boolean algebra was not paid much attention to. The famous mathematicians in continental Europe called it unmathematical and philosophical odd. Boolean died shortly after his masterpiece "law of thinking" was published. Until then, when computers were invented, the great value of Boolean algebra was fully embodied. Digital computers used binary to process data, and Boolean algebra was the most basic principle.
Or Linus, when we first created Linux, we wanted to create an operating system of our own out of interest. Thanks to his powerful programming capabilities and deep research, his operating system kernel was quickly realized. He sent the source code of his operating system to the internet and received support from many people. programmers from all over the world have jointly improved his system, it has become a lot of Linux today (but this is a strange thing for non-technical people ). There is an online article "Linus, looking for laughter for a lifetime", which tells the story of Linus.
The famous painter Van Gogh has made his work worthless and has been miserable. Van Gogh said: "What do I do in the eyes of most people? A useless person, an abnormal and annoying person, a person without social status and will never have social status. Good. Even if this is a fact, I want to express in my work what is the heart of such an abnormal person, such an unremarkable person. This is my ambition. The main foundation of it is love, not hate, calm, not enthusiasm. It is a fact that I often fall into great pain. However, my heart is still quiet, pure harmony and music. In the shortest room, I found a picture in the dirtest corner ." Van Gogh's work was not recognized by the public until he died. This is a great tragedy.
Contact our daily lives, learn the gods who are very good at learning and really like to learn. There are great gods who are full-day labs and coding and welding circuits. There are all kinds of cool people who do what they do, in fact, it is very simple, that is, stick to what you want to do. What they have done, namely, Boolean, Linus, and Van Gogh Stick to what you want to do, even if it doesn't make sense. What they stick to may one day become a treasure of human society.
But this is an ideal situation. I think the most important thing in an ideal society is that everyone can do what they like most without having to consider livelihood issues. In such a society, talent can Maximize your talentTo Focus on everythingIn the end, the overall social development is better.
In the real world, we have to consider many practical problems, especially in countries with many people in China, great life pressure, and imperfect social security systems. As a result, I went back to the previous issue. There was no essential difference between God and the players in various aspects of the game, but the social needs were different.
What I think is the meaning of life. In my opinion, the most important thing is Do what you want to do that is harmless to others. If it happens to be what society needs, it would be better off.. I am a very lucky person. What I want to do is in line with social needs. I can do what I want without worrying about too many practical problems; I have to pay much less to get some results. With this lucky condition, I can naturally do better as long as I learn to think more and work harder. At the beginning of my college career, I never thought about how to find a job. I never thought about how to be a so-called great god. I just It's easy to do what you like..

Of course, if you are not so lucky, you do not need to be too pessimistic. Everyone's interests are not inherently unchangeable, but can also be cultivated later. As far as I was concerned, I had a very clear interest from an early age, so during college, My strong interest provides a huge source of motivation for my learning.. Select a direction that you are interested in, at least not disgusted with, and stick to it in a down-to-earth Manner, you will surely be able to achieve your satisfaction.
For more thoughts on my interest and many other questions, see this article http://blog.csdn.net/jzj1993/article/details/39657051.
This article is the most comprehensive and comprehensive consideration I have made so far on technical learning and other related issues.
