1. Don't treat the kindness of others as cowardice, but treat the humility of others as your reckless capital. No matter how hot your heart is, it will cool down, and no matter how big your measurement is, it will be unbearable. Don't always be so arrogant and opinionated. When you claim to be a favored son of heaven, you may be like dust on your feet in the eyes of others. Don't be angry with others. At home, you are the little prince and princess of your parents, but outside, no one needs to look at your face. You can be spared. Don't gossip about others behind their backs. Other people's business is always other people's business. If I do it with you, I will never say anything again, but I will always leave messages for others. Don't laugh at anyone, it is a reflection of your low quality. Why should we lower our value because of others' ignorance? 6. Don't make excuses for your mistakes. A mistake is a mistake, and it is futile to whitewash it. Explanation is cover-up, and cover-up is the beginning of error. 7. Don't complain that others are indifferent to you and don't pay enough attention to you, because in your heart, people are divided into three classes. 8. Don't resent the injustice of heaven, it will never be heard, but your youth is fading away in your sorrow. 9. You don't like everyone you know, so don't expect to win everyone's favor. So you don't have to cater to anyone, just be yourself. 10. Don't lose your temper because of other people's mistakes. Not worth it. Being angry, angry and sad is the cruelest punishment for yourself.
