"Dark Time"

What is dark time

What is dark time? You walk, buy vegetables, wash your hands, take the bus, go shopping, travel, eat, sleep, all these times can be called "dark time." I understand that the dark time is to spend the time that I usually unconsciously, see that it has gone through the hours of full use up. These times in the eyes of the author can be used to think about problems, to chew and digest what you see and read at ordinary times. This period of time seems insignificant, but the accumulation will have a huge effect, so good use of thinking time people, can be virtually more time than others, so that in practical sense can live many years more than others.

Everyone's life is like an hourglass, the amount of sand inside is roughly equal, the difference is that some of the hourglass neck is thinner, some of the hourglass neck thicker. The finer hourglass of the neck catches every grain of time, even if the amount of sand is the same, and can have a longer life.

Suddenly Lenovo South Korean president Lee Myung-bak's sentence " my 12 years equals others 24 years ", life is a gradual accumulation of the process, but some people accumulate more, some people accumulate less, sometimes you may overlook the accumulation of a day, but even if the gap is very small, But the accumulation of time will be very different (this is a bit like you think 2 is very small, but if 2 of the n-th side that ... ），

Learn to do something consistently

In a field where you are interested in persistence to focus on, just choose a not too unreliable direction, and then concentrate on the drill down, the final must be a master or extreme master.

The power of habit will be far greater than our imagination, so strive to develop their own good habits. In fact, it takes 21 days to get used to it, so don't make excuses for your inability to correct bad habits.

Often thought has been

We often hear that the word "mental age", people who think a lot, tend to have a greater mental age. Someone with 10 years to understand a reason, because they are passive understanding-only in the reality hit his face when the pain, after the pain is not remember always remind himself, the results quickly changed the brain after the second encounter with the same hole when the time has been forgotten once fell over, like this efficiency, Unless every day falls in the pit, otherwise the efficiency of forgetting is always greater than the loss of long memory. People who are good at thinking time can remind themselves of important things and turn temporary memories into hard-coded behavior habits. Everyone's watch goes as fast, but everyone's life is not. To measure how many years a person lives, it should be calculated by thinking time. To cite an extreme example, if a person is born to stay in a specially constructed sterile protection room for him, without social intercourse, without knowledge acquisition, spent 18 years, you will think he is an adult? Think that time is equal to everyone is an illusion, think others one day, I also someday, in fact, is not the case at all. If you are learning a major, you use the number of days you put into the measurement, it is easy to create an illusion, think that a lot of time, but in fact, the "time to invest" in itself is absurd, the actual investment is the product of time and efficiency. You can "put" a lot of time on one thing, but find that there is no progress, because you do not spend all day doing what you want to do, what you want to learn is resident in your brain, always giving it the highest priority. When you are walking, when you are eating, when you dream, it is this thing that hoping at, your CPU is always assigned to it, this time your thinking time is used to the extreme, the time you put into really equals the actual elapsed time, because your CPU is full.

If you have a summary of the habit, you spend a period of time after summing up the amount of time invested in such fields, it is recommended that you do not roughly calculate how many days after work to pick up the book to look over, because you may find that the book is often turned, but the understanding is not much deeper, the surface spent a lot of time, the benefits are Because reading and remembering things in the book is only memory, and does not involve reasoning, only by reasoning to understand a thing deeply, see others can not see the place, this part of the process of reasoning is your thinking time, but also occupy a significant proportion of the life of the "dark Time", you walk, buy vegetables, wash your hands, take the bus, shopping, Travel, eat, sleep, all these times can become "dark time", you can make full use of these times to think, Chew and digest what you normally read and do, so that your understanding can be divorced from the scripted level. This may seem trivial, but over time it will have a huge effect.

Concentrate on doing one thing

Programmers know that task switching takes a lot of extra expense, and in layman's terms, you first need to save the current context so that you can switch back smoothly the next time, and then load the context of the target task. If a system keeps moving back and forth between multiple tasks, it can take a lot of time to Daoteng on the context switch, virtually wasting a lot of time. In contrast, if only one task is done, there is no such loss.

That's why people who focus on time use much more efficiently than people who don't focus. The dark time of the task switch seems to be very low, even many people think that "multitasking" is a good thing (sometimes it is), but the accumulation of time will be found that the cost of switching more and more.

In addition, the brain must have a certain amount of time to "warm up" when it starts a task, and this time varies from person to person and can be changed by practice. For example, writing a program is very high, suddenly be called to open a meeting, write half of the code put there. How long will it take you to get back into the state when you're done? Or, you are debugging the program, you have spent 20 minutes of the bug may be related to the code to understand the back and forth, the heart built a rough map, just then, you are called to open a meeting (:D), after the meeting will come back, imagine, It's going to take some time to think about what you just figured out.

The ability to train yourself to get into the state quickly

Being able to quickly get into focus and be able to stay focused for a long time is the two most important habit of effective learning.

The ability to get into the state quickly can be exercised, which, according to my personal experience, can be reduced to at least 3-5 minutes. But it is hard to achieve it in such a short time to be fully in state.

The so-called fully-entered state, for example: you read a 3-hour book, or debugging a half-hour program, is often full of related things, all this knowledge is active, in other words, all the relevant memory neural network in your brain is activated, to achieve such a forget the time of the passage of the "immersion" State (psychologically called "streaming experience"), not three or two minutes of things. And once this state is destroyed, the efficiency of the intangible will be greatly compromised.

This is why I always tend to create chunks of time to read important things, because it helps to "immerse" in it, so that new knowledge can be fully integrated with the various existing knowledge in the brain, which is very helpful for deep memory. To take full advantage of dark time, not only to be able to enter the state quickly, another important habit is to keep the state for how long (mental energy).

Learn to resist interference

Only with super-strong anti-jamming ability, can effectively use the above mentioned in the various dark time. Anti-jamming ability can also be practiced out.

Frequent use of various fragments of time to read and think is very helpful in quickly concentrating and maintaining attention.

Think about whether you're wasting your time?

The root of wasting time is

1. Avoid difficulties (in the face of difficulties to avoid, now the leadership let me deeply appreciate if you want to avoid difficulties and then your position will soon be replaced by others, the boss hired you to solve the problem rather than let you to avoid the problem)
2. refuse to learn (do IT industry, especially the front end, if you don't learn new things in one months will be out of the out)
3. Confusing tools and problems (the computer was originally designed to improve people's productivity, but eventually became the source of most people to kill time, wasting time, trying to keep reminding themselves not to forget the ultimate purpose of the computer?) To see a movie? ）

Writing is for better thinking.

"I often summarize what I've learned before walking and going to bed, thinking about the problems left behind, and after a period of reading and thinking, a general framework of knowledge will gradually emerge in my mind." Then I will write it down, however, I am often very surprised to find that when I write, the new content is still streaming out, just as my keyboard will think the same. "It was a sentence in the original, which impressed me.

1. The benefits of writing include the following points:
2. Writing is a reminder of the mind
3. Writing is the caching of thinking
4. Writing is a conversation with yourself.
5. Writing is communicating with others.
6. Sometimes, language can think for itself.

What is your irreplaceable and core competence

The individual's core competence is his unique combination of personality, knowledge and experience.

The IT industry is crowded with millions of smart people, what is the real difference between them? It's not what you learn, how deep you learn, how much IQ you have, but how you have a unique combination of personality, background, knowledge and experience that no one else has. If this combination,1, Unique, 2, in practice is valuable, 3, with sustainability, then you have the core competitiveness . Therefore, when designing their own development route, should maximize and exert their own unique combination, rather than seek individual transcendence. And the way to build their own unique combination, mainly through practice, followed by the conscious construction.

The following knowledge and skill sets are of considerable non-fungible nature:

1. Expertise : Becoming a specialist in a professional field, the stronger your professional skills, the more irreplaceable you will be in this field. This is not much to say.
2. cross-cutting skills : problem solving, creative thinking, judgment and decision making, critical-thinking, communication, Open mind, and more.
3. Learning Ability : Strictly speaking, learning ability also belongs to cross-domain skills, but because it is too important, and across any field, so independent out. How to develop learning ability, the most effective way I know so far is to keep learning and thinking about new knowledge.
4. personality Elements : Strictly speaking, this also belongs to the cross-domain skills, the reason ibid. Some of the traits I believe are important include: focus, perseverance, self-examination (awareness of the ability of the problem, which is the premise of improvement), curiosity, self-confidence, humility (self-confidence and humility are not contradictory, the former is to believe that others can do themselves can do, The latter is not always think that you are sure the right is necessarily right, Keep an open mind) and so on.

Why do we always say that many times we have to experience it before we can understand

1, personal experience : personal experience of a negative event brought about by the emotional memory than to see or hear other people suffer from a similar incident felt much stronger, the formation of negative reflex is far more lasting. We do have a degree of empathy, but psychological experiments also show that we cannot really empathize with others ' pain from strength.

2, the story of Others mouth . The story of someone else's mouth may be just one aspect of things, inevitably influenced by their own ideas and bias, each of us with tinted glasses to see the world, an objective and comprehensive description of a thing very few people can do. Other people's stories may just be their thoughts, and it may be entirely another idea for you to experience the same thing yourself.

3, why . When someone tells you a reason, it's often just telling you how, and it's hard to say why you're doing it, let alone "why do you have to do it" (because they're not necessarily able to say so). It's hard to convince yourself that a option is better than the B option until you finally hit the south wall on a certain road before you hear the logic and irrefutable evidence.

4, the world is complex . What's more, there are times when people can't exactly assure you that the a option is better than the B option: for example, good learning is not necessarily a promising future;

5, The future is uncertain. Humans are born with the need to seek certainty and to control the needs of the small world around them. We always want to hear "you just have to do this, you'll be able to do that in the future" kind of heartwarming. However, contrary to our illusion of control, there are too many factors in the world that are uncertain, except that their own factors are more controllable, and the external opportunities are almost entirely not controllable or predictable. We can only prepare our minds at most, and try not to miss opportunities. And that's why you almost never hear enough convincing evidence to tell you that "you just have to ...", because success doesn't depend solely on personal factors. Personal factors are often just a non-sufficient and non-essential condition for success, so-called man-in-the-people, but not pessimistic, because there is no doubt that improving personal factors can greatly increase the odds of success.

6, Other people's truth, their own things . We often say something like, "You're right, but it doesn't apply to me here." In this case, your own things and other people's things often have such or such a small or big difference, if we do not want to listen to others ' opinions, it is easy to convince ourselves that "the situation is not the same, So the truth does not apply "(and in fact, exactly what the circumstances are not the same, why the reason does not apply, is not really applicable, we simply do not go to the bottom of it). In addition, friends give the truth or story is always with his original experience of the context of the details have inextricably linked, you write down the truth and story of friends, but also this truth and his experience in the context clues to hook up, so when the similar situation occurred, Your memory system will be able to extract from contextual clues what friends were saying to you ("Looking for the Lost Self"); However, this memory extraction mechanism also has his weaknesses, that is, when you are experiencing situations that are less similar to the situation your friends were experiencing (though the abstraction may be a matter of nature), You won't remember the truth that he used to say. That's why many times we find ourselves listening to a bunch of things that don't work in your life. The so-called "ingenious", is that those who are good at grasping the essence of knowledge, comprehend by analogy, will reason outside the surface is not similar but the essence of the same problem areas of the people.

In addition to a lot of introspection to observe themselves, in the face of the problem is more abstract nature is also a powerful way, it is the surface of the non-similarity hinders the transfer of knowledge, we often say that some people are good at seeing the nature of things, such people are often the smart, because they are more able to extrapolate, Extend the sense of one place to another that looks very different.

7. cognitive dissonance and self-defense . If we have a psychological inclination before we hear other people's reasoning, then even if someone gives a compelling reason, according to the theory of cognitive dissonance, we will try our best to defend ourselves, and because the world is complex, we can almost always find excuses for defending.

8, failure is success . Sometimes, we do need to draw lessons from the process of hitting the south wall (especially for those who have not yet traveled) and reach the other side of the road to success. From the point of view of the information collector, there is no success or failure in the world, and the information disclosed in the failure is no less than the information in the event of success, and perhaps more is often available.

9, emotional control . After a failure, we feel more justified in doing the "right" thing. Without a bad memory of failure, it is hard to think rationally that the present practice is more appropriate, and it is difficult to feel emotionally strongly about the "sense of correctness" of doing so.

10, Nature . We have many evolutionary choices rooted in the brain that are always the highest priority in judging and making decisions. So even if someone convinces us that we should think about it in the long run, he has eaten only his present loss, but a voice in your heart is still screaming, "Let him go!" ”。 Therefore, we often need to use rational voice to persuade the inner primitive people. Fortunately, we can, if we have to understand ourselves first.

11, habits . We often say, "it's easier said than done." The power of habit is far greater than our imagination, many times we will have this experience: heard a very reasonable words, but not a few days, found themselves back to the original old look. Even if oneself in a predicament to understand some very important truth, decided to encounter similar situation in the next time do not make the mistakes of the previous, however, when the real encounter the next situation when you find yourself unconsciously made the same mistake, who said that people will not two times into the same river? Perhaps the best way to deal with our strong habits is to write down what we think is right ( whether it's through difficulty or failure, or to see the book or hear what others are saying), and often take it out and look it over. In fact, my experience is that in writing down our brains will go into the rational analysis module, further testing and reasoning for those reasons, the more we look at a sense of detail, in-depth, comprehensive, the brain left deep impression, from the memory processing point of view, this is called deep processing, The result is that the memory is associated with more extraction cues and can be evoked in more scenarios (rather than being directly covered by previous habits ).

If you have experienced it, you must understand it?

1, very silly very naïve reflex . Conditioned reflex is a system that is too foolish and naïve--we often choose to abandon our practice after we touch the rebuff. But in fact, hitting the south wall does not necessarily mean that the practice is wrong, it may just be bad luck. Not getting good results doesn't mean that your process is wrong. Similarly, the correct result does not mean that the method must be correct. The objective approach is to focus on the process rather than on a single result-because the good process may occasionally fail, but in the long run, the good process will inevitably lead to better results.

2, cognitive deviation . We have a variety of systemic cognitive biases: we often make wrong interpretations and attribution to things (even if we are ourselves), sometimes even "lookers, onlooker sees most."

3, the emotional system . We strongly rely on the need to experience a negative event to learn, because our usual decisions and judgments rely strongly on the output of the emotional system, if a thing "feels right", we have no good reason to persuade ourselves not to do it, if a thing "feels wrong", It is hard to persuade yourself to do it, no matter how good the reason is. This strong reliance on the emotional system makes rational evidence weak in the face of strong emotions. In fact, our intuition does have a lot of time to be very spiritual, but there are many times it is ineffective, the right way is not to listen to the intuition of generalize or generalize to listen to, but as a heuristic judgment, and then use their rational brain for further objective, logical test (Critical thinking). We are able to harness the emotional system to a certain extent , and the emotional system is, after all, one of the decision systems in our evolutionary toolkit, not all. Also always remember that the emotional system is just a rough decision-making system, and it is often used to adapt to ancient society rather than to modern society.

No need to experience or understand (the power of Reason)

Our depth of thinking about things is often not enough, and after a shallow level of thinking, if our emotional system or intuition has given us a tendency, few will continue to think deeply and begin to move on. This rush of attitude is often the origin of failure, after a wall, we passively "let the facts Tell us" a scheme is not feasible, let the facts replace us with thinking and reasoning, we have obtained information from the failure, we know why the previous method is inappropriate, This is the reason why we feel that we have to experience it at some point. However, this does not mean that at any time we can only "do it and then discover ...".

The most powerful ability of man is social learning--the ordinary people learn from their mistakes, and wise men learn from others ' mistakes.

One of the most powerful human abilities is induction and reasoning.

We can think carefully, rationally, and weigh the pros and cons of each choice, not just the emotional judgment . Assuming we face two choices, A and B, we can combine the experiences of others and use our own reasoning ability to infer the various possible pros and cons of a or B option separately, and we may further collect more information from others to make our judgments more reliable , Or we can make some estimates of the upper and lower bounds of the risk, in short, we try to let the imaginary characters in our brains go through failure-we find that a path is not feasible by reasoning, and we avoid the reality of touching rebuff. The farther we go in the brain, the more stable we go in reality . The more times we fail in the brain, the less we fail in reality. Until it is impossible to know the answer in advance (the problem you are facing is something that no one has explored before), you must explore yourself, and at that time, we are no longer repeating the old way, but the seeker, the innovator, because we stand on the shoulders of others.

Written in the last

One of the most important abilities is the ability to learn from the mistakes of others, often such people can quickly walk in front of others, jumping in places where others fall.

This is an information society, the lessons of all, the knowledge of all at an unprecedented speed, the internet as the media spread, no matter what we focus on topics, always quickly find a pile of books, forums, Web pages, but can get knowledge, avoid doing other people do push-ups, see you have a pair of recognizable eyes , and a thoughtful mind (see " How to think clearly " (This is what I'm going to write next))

And because a good book and delay their time to sleep, want to say to themselves, love themselves, follow their own inner thoughts go, insist on what they want to learn, I believe that the harvest
