16. Life is like a steep mountain; to taste its true essence, one must climb relentlessly toward the peak.
17. Life is like a game of chess; those who only defend without attacking have no hope of victory.
18. Life is a struggle, encompassing both the pursuit of career and the tempering of life.
19. There are no paths in life; if there are, they are paved with youth and life itself.
20. Life is a song, and friends are its most melodious notes; life is a painting, and friends are its most beautiful strokes.
21. Once the human heart is shackled by fame and fortune, the consequences can be dire. Wise people view wealth and glory as fleeting clouds, dreams, or dew on the grass, while the foolish are blinded by power and profit.
22. "Strength comes from lack of desire" and "to live indifferently to fame and fortune" represent the highest state of non-attachment. Everything in the world returns to the concept of "tranquility" (Dan): clarity of purpose, elegance of character, and a calm approach to life. From this, we should contemplate the profound philosophy of "desire versus non-attachment."
23. Life passes like a white horse glimpsed through a crack. Properly managing the degree of our desires allows us to experience more happiness within our limited lifespan: enjoying family reunions, feeling deep friendship, and marveling at the beauty of nature. When facing temptation, we must use reason to conquer desire and avoid becoming slaves to fame and fortune.
24. Students should not be passive recipients of knowledge but active subjects who question, discuss, and discover. When students encounter difficulties, teachers should guide and inspire them, which is far more effective than simply forcing knowledge upon them.
25. Asking "why" more often may make life extraordinary. Scientific progress stems from the pursuit of truth; in life and learning, we must think critically instead of going through the motions. By constant questioning and humble inquiry, we can learn more deeply and become wiser.
26. Learning is not just about ability; it also involves self-esteem and vanity. It is not shameful for those of low status or ability to seek guidance from the powerful or knowledgeable. Conversely, those in high positions often find it embarrassing to seek help from those perceived as inferior.
27. Books are vessels for the wisdom of our ancestors, deserving of respect and inheritance. However, since all human thought is limited, books may contain errors or outdated ideas. Therefore, we must read critically and objectively, choosing healthy books that inspire and enlighten us, rather than blindly following them.
28. Highly efficient people know how to utilize time. Time is both ruthless and fair. Those who cherish time will seize opportunities and create more value than others within the same timeframe.
29. Ambitions differ in height. Just like climbing mountains, some vow to reach the highest peak, while others are content with hills. While climbing high is arduous, the view of "seeing all mountains appear small" is a realm that those who only climb hills can never reach.
30. Unless we apply book knowledge to practical experience, it remains merely theory.
