Convergent Nature

A group of children are bullying you, not what you did wrong, but because they need to find something to do together, they do not really hate you, they just need a common goal, the use of drugs based on the same principle;
Geeks use drugs in order to establish a social bond between them;
Because drugs are illegal, they create a common sense of rebellion by using them together.

the relationship between the old employee and the newcomer

If there is a real external competency test, it will be less painful to stay at the bottom of the hierarchical relationship;
The new team will not resent the old team's skills, he hoped that one day he can, so it is very happy to have the opportunity to ask the old players, the old players also produced mentoring glory;
The most important thing is that the status of the old players is acquired through their own status, not by crowding out others;

conservation of pay and return

You can think of entrepreneurship as a compression process in which all your working years are compressed into just a few years;
You are no longer a low-intensity job for 40 years, but work at extremely high intensity for 4 years; in high-tech field, this kind of work intensity brings rich returns, the higher the efficiency, the higher the extra return;
Conservation law: If you want to earn 100 dollars, you will have to endure the pain relative to 100 dollars;

money doesn't mean wealth .

Wealth is the most basic thing, what we need is wealth, food, clothing, cars, travel and so on are wealth;
The myth of the pie: Many people think that the world's total wealth is fixed, if the rich take all the money, the other people become poorer;
The wealth of human history has been constantly growing and destroying (net growth in general);

Understanding Wealth Growth

Craftsmen create a commodity is to create wealth, with the advent of industrialization, fewer craftsmen, the current existence of the largest manual artists group is the programmer, the programmer sits in front of the computer can create wealth;
The wealth created does not necessarily have to be sold to achieve value; The discovery of penicillin makes us all richer;
Hackers often develop open source software for everyone to use for free, so that their work to donate to the community;

The most basic principle you must keep in mind is: to create what people need is to create wealth;

focus on wealth differentiation

The rich do the same things as ordinary people do everyday;
They do not have to work at all, they are still working, not because they feel social pressure, but because doing nothing makes people feel lonely and depressed;

Select

A society in which the whole is very wealthy but the individual is relatively poor; a society in which one is very wealthy but a whole is very poor; I will choose the former;
A society needs the rich, not primarily because you need the money of the wealthy to create jobs, but because of what they do in the process of getting rich;
If you make Henry Ford Rich, he will create a tractor so that you no longer need to plough the horses;

Large Companies

Big companies will make every employee's contribution average; in big companies, individual performance cannot be measured alone, and the rest of the company will drag you down;

the essentials of Getting rich

To get rich, you need two things: measurable and scalable; small groups are measurable; Jobs said that the success of entrepreneurship depends on the first 10 people who joined the company, I basically agree, I think the real decision success or failure is actually only the first 5 people; High technology equals scalability;
The best defense is offense, and if the technology you develop is difficult for a competitor to replicate, that's enough, so you don't have to rely on other defenses, and you start off with a harder question, and then choose the harder option for all sorts of decisions.
Generally speaking, this is a good principle of doing things, if you have two choices, choose the more difficult one;

Number of users

It would be a good choice if your company had the privilege of being bought; the best way to get a buyer to pay is not to let the buyer see the possibility of profit, but to let them feel the fear of losing, potential buyers will try to delay the acquisition, for the buyer, the strongest acquisition motive is to see the competitor may buy you; The second-strongest takeover motive is to make them worry that if you don't buy you now, your high-speed growth will make future acquisitions expensive; The two motivations are ultimately the number of users; The user is the only proof that they have created wealth;
You should be the same as the buyer, the number of users as a test indicator;
Optimize the company like optimization software, the number of users is to judge the performance of the company's indicators;

Designer's TasteA good design is a symmetrical design;

There are two kinds of symmetry: repetitive symmetry and recursive symmetry; recursive symmetry refers to the repetition of elements, such as veins on leaves;
(Eiffel Iron Ride)
In writing, you will find symmetry everywhere, phrases, sentences, novels of the plot are so;

good design is to imitate the design of nature;

Nature has solved many design problems in the long-term evolution, and if your design is close to nature, he will not be very poor;

Good design is a re-design

It's good to have someone do it all at once. The expert's approach is to complete an early prototype, then propose a revision plan, and finally throw out the early-morning prototypes; throwing away early prototypes is a need for confidence, and you have to be able to see where it can be improved; people who have just begun to learn to paint are often reluctant They felt it was not easy to paint it, and the result might not be as good as now;
The idea is very dangerous, you should cultivate dissatisfaction with yourself, it is normal to make mistakes, you should be brave enough to admit mistakes and be bold in correcting them.
The same is true of programming technology, and no modification is too much, continuous refactoring, to ensure that each modification is simpler than before;

the growth of the company

There are two ways in which new things are accepted by the market, one is the way of growth, the other is the Big bang, and the natural growth example is a self-reliant entrepreneur in the garage, and after developing a certain product, to the market, without any marketing and propaganda, out of the initial few users to the word-of-mouth effect, A gradual increase in the number of user data;
The Big Bang example is the involvement of venture capital, in the market to fight flag drum propaganda, immediately access to a large number of users;
In the end, the natural growth boom produced better technology that could bring more wealth to the founders.
