21. Everything in the universe follows the principle of Yin and Yang: light exists alongside darkness, righteousness with error, advancement with backwardness, peaks with troughs, prosperity with adversity, joy with pain, strength with frailty, gain with sacrifice, labor with rest, speed with slowness, closeness with distance, beauty with ugliness, passion with hatred, and glory with shame. All things follow this logic; the balance of more or less determines the difference.
22. The older generation often suppresses the self, living cautiously and exhaustedly; the younger generation often becomes too self-centered, living with constant worries and exhaustion. In truth, one cannot live solely for others, for losing oneself yields only social recognition; nor can one live solely for oneself, for ignoring others yields only self-gratification. Since humans cannot exist in isolation from society, the essence of life lies in balancing the relationship between oneself and others, and between the inner and outer worlds.
23. 蟻穴雖小，潰之千裏.
24. The world's number one product is not the car, but yourself. Before you can successfully sell yourself to others, you must first sell yourself to yourself one hundred percent.
25. The wise seek solutions within themselves; the foolish seek them from others.
26. The greatest tragedy in life is not losing too much yesterday, but drowning in yesterday's sorrows. Do not care too much about certain people; if asked, simply say you have forgotten. No explanations, no sadness. Whether they stay or leave is insignificant. To fall helplessly into an endless whirlpool, counting the grievances of passing years, is merely to piece together a sense of sorrow. In the end, everything is lost to time; the bitterness and pain are understood only by oneself.
27. A flock of sheep follows blindly, which is the tragedy of the sheep. Life is a voyage, and only those with clear goals achieve their true expectations. Those without goals are merely following the crowd—they may arrive, but they gain nothing because they do not know why they are there. Do not mistake the expectations of others for your own goals; cultivate the ability to think independently and move forward along your own path. Do not drift with the tide, do not follow the crowd, do not bind yourself, and do not follow blindly.
28. Opportunities are never truly lost; what you miss, someone else will catch. When you let your pain dock, happiness will anchor elsewhere.
