First, the book theory is noble. The first generation of scholars absorbed the world around them to think, rearranged it with their own hearts, and then showed it. When you go in, it is life, and when you come out, it is truth; When you go in, it is a momentary behavior, and when you come out, it is an eternal thought; It's a living thought when you go in. It can stand and walk, sometimes stable, sometimes soaring, and sometimes enlightening. The height of its flight and the length of its singing are exactly proportional to the mind that produces them. -Emerson
Second, give full play to intangible capital (time and energy to think with ambition) and assist tangible capital (capital, human resources, raw materials and social relations), which has never been done before, and do what people dare not do today. -Kōnosuke Matsushita

5. The ultimate value of life lies in the ability to awaken and think, not just in survival. -Aristotle
6. If others think about mathematical truth as deeply and continuously as they do, they will make the same discovery. -Joan? Edwards
VII. The combination of thinking and practicality can produce clear concepts and find some simple methods. The discovery of these methods stimulates self-esteem, and the accuracy of the methods can satisfy the intelligence. The original boring work is interesting with simple methods. -Rousseau
