First, if you talk too much, you will lose; if you think too much, you will be afraid. As the saying goes, silence means that people will think carefully before speaking, but caution does not mean multiple thoughts. The more time he spends thinking about something, the more afraid he is of doing it. This is the same as the pony in the story of the pony crossing the river. If he had bravely stepped across the river from the beginning, the story wouldn't be so complicated. This is because the time of thinking and the constant interference of others will lead to such a tortuous story. Therefore, it only takes a certain time to think, and people will naturally become timid if they think too long.
Second, think without learning to make practice lazy. Let's imagine that if a person only reads without thinking, he will fall into the quagmire of bookishness and blindly believe the knowledge in books without thinking, which is very harmful. On the contrary, if a person just keeps thinking instead of studying or practicing, then he will become very lazy and just sit there and daydream for a long time. Therefore, if you are too biased towards thinking, you will be bound by thinking and become lazy.
3. Empty talk about making mistakes and rejuvenating the country. This is what Premier Wen said a few years ago. Empty talk will only delay national affairs, and only action can save the country. Empty talk becomes empty talk because it takes too long to think, so it's hard to do it. So thoughts and actions are like human legs. If one is too long, the other will be stunted. So we should avoid giants in thought and dwarfs in action.
