Selling your body is hard to succeed without appearance. Selling your soul is much simpler; you just need to be shameless. Some truths are soaked in blood, and teachers don’t teach them, nor do parents mention them, because they are too cruel. A few things to cherish: First, if you care too much about what others think, you will easily end up as someone else's underpants. You have to catch whatever others let out. This world doesn’t exchange sincerity for sincerity; we just exchange people. Many times, it’s not about letting go of someone; it’s about learning to let yourself go. Second, the poor like to show off, while the rich are good at pretending to be poor. Those with depth are pondering, only shallow people act as contrarians. People are really interesting; the more lacking they are, the more they want to prove themselves, and the more fulfilled they are, the less they care to compete with others. When you know nothing, you pretend to understand everything. Third, you want to get angry, but you hold it in; that’s a skill. You want to give up, but you persist; that’s ability. In middle age, you need to learn to control your temper; you can express anger, but you cannot express it in anger. Fourth, if you insist on reminding a fool, be careful, as you might not only offend the deceiver but also make the fool feel that you are insulting his intelligence. What can persuade a person is never reason but hitting the south wall. What can wake someone up is never preaching but hardship. Fifth, no quality can ensure peace of mind. A person’s high-mindedness requires tolerance; otherwise, high-mindedness becomes arrogance. A person’s kindness requires decisiveness; otherwise, kindness becomes weakness. A strong person must have respect; otherwise, strength becomes violence. A rich person must practice frugality; otherwise, wealth becomes extravagance. A noble person must be humble; otherwise, nobility becomes arrogance. Finally, without suffering, one cannot receive blessings and fortune; without hard work, one cannot attain wisdom. If you are currently experiencing suffering, I hope to give you some strength.
