When interests arise, friendship can change. Friendships devoid of self-interest are precious but fragile, as they have yet to withstand the tests of reality. Life is inherently unfair, and we must learn to adapt to it. In social interactions, avoid showing off: if you wish to gain enemies, act superior to your friends; if you wish to gain friends, let your friends shine more brightly than you. To earn the respect of others, one must possess true talent and knowledge. A person with genuine ability can stand tall without apology, for living by one's skills is the most rewarding way to life.
