During my long career, I absorbed several simple general ideas and found these ideas very helpful for solving the problem. I will describe five of them now. Then I will ask you a very difficult question. It's really hard, because the question involves how to turn $2 million in startup capital into a number-2000 billion, which is a massive success. Then I will try to solve this problem through my general ideas ...... my first useful idea is: the best way to simplify the problem is to first decide on big things that can be judged without any effort. The second one imitates Galileo's conclusion that scientific facts can only be revealed in mathematics, and mathematics is like the language of God. Galileo's theory is also useful in a messy real life. In the world where most people live, without smooth mathematical thinking, it is like a single-legged person in an unusually fierce competition, and is doomed to fail to win. The third idea is that it is far from enough to think about the problem in a positive way. You must also learn reverse thinking. Otherwise, a village employee wants to know where he will die, so that he will never go there. Indeed, many problems cannot be solved through positive thinking. That's why the great modern mathematician Carl Jacob said, "reverse thinking always requires reverse thinking. "Rythagoras proves through reverse thinking that" the square root of 2 is an irrational number ". Article 4 useful ideas are that the best and most practical wisdom exists in basic knowledge. However, there is an extremely important constraint: You must think in an interdisciplinary manner. You must use the simple and easy-to-learn principles that you will learn in the first-year course of each basic discipline. When you have mastered these basic concepts, the problems you want to solve will not be restricted, because universities and many commercial institutions have their own limitations due to their division into distinct different disciplines and departments, they are highly opposed to taking risks out of the predefined areas ...... the fifth useful concept is truly great. Outstanding results are usually only the results of the combination of many factors. For example, tuberculosis has long been cured with drugs, and at least for a while, the prescription is a mix of three different drugs in proportion. Another outstanding result, for example, the plane can take off and follows the same model.
