Developing the ability of association and independent thought is essential. By accumulating vast knowledge and maintaining an open mind, one should possess the courage to think outside the box and avoid being bound by any restrictions. For instance, when solving a math problem, instead of focusing on a single solution, one should seek a universal method applicable to all similar problems.
Humanity is inherently good at birth, but growth, environment, interests, and habits shape who we become. As the saying goes, "It takes a moment to fall into bad habits, but a year to build good ones." A bad habit like gaming can instantly erode the good habit of reading, while breaking a habit like smoking often requires a long period of persistence.
"Trends" refer to the timing, objective circumstances, and the tide of the times. To "understand the trends" means to recognize, master, and adapt to objective laws and circumstances to pave the way to success.
One should learn to be flexible in life and avoid clashing head-on with immovable obstacles, as the consequences of such actions are predictable.
To solve a problem, one must address its root cause. Similarly, to defeat an opponent, one must target their weakest point, whether it be their emotions, social connections, or character. By identifying and exploiting these vulnerabilities, one can gain the upper hand. For example, a person prone to irritability can be led into a trap by intentionally provoking them.
