1. Be a simple person, down-to-earth and pragmatic. Don't indulge in fantasies. Don't bother yourself.

2. Learn to think, have a clear mind, understand your own insignificance, and avoid being narcissistic. Don't force yourself to be the best in everything, because you are not as strong as you think!

3. Everyone is an independent individual. We really can’t live without anyone!

4. Don’t overestimate your power in the group, because when you choose to leave, you will find that the sun still rises even without you!

5. Society is hierarchical, and many things are unfair. Don't complain because it's useless.

6. Learn to tolerate people who hurt you, because they are very pitiful, everyone has their own difficulties, and it is not easy for everyone.
