It's very reasonable. But it's hard to do, try your best. 1. Do not take other people's kindness as weakness, and their tolerance as your capital to run wild. Even the hottest heart will cool down, and even the greatest tolerance has its limit. 2. Do not be so arrogant and self-righteous. When you think you are a proud son of heaven, in others' eyes, you may just be like the dust under their feet. 3. Do not vent your small temper on others. At home, you are your parents' little prince or princess, but outside, no one has to care about your mood and can leave you alone, leaving you lonely. 4. Do not gossip about others behind their backs. Other people's affairs are always theirs, not yours. Talking about them won't add anything to you, but will always give people something to talk about. 5. Do not mock anyone, which shows that you have low quality. Why should you reduce your value because of someone else's foolishness. 6. Do not make excuses for your mistakes. If you are wrong, then just admit it. Explaining is covering up, and covering up is the beginning of mistakes. 7. Do not complain that others are indifferent to you or do not value you enough, because in your heart, you also classify people into different levels. 8. Do not hate the injustice of heaven, it will never hear you, and your youth will pass by in your melancholy. 9. You do not like everyone you know, so do not expect to win the favor of all people. Just be yourself.
