I've been thinking about some of my principles. I won't categorize them for now; I'll write them down as they come to mind, and I'll keep adding to them, hoping they'll be useful to everyone. This is divided into two parts: a brief overview and the specific reasons behind these principles.

1. **Do not criticize, condemn, or complain.**
2. **Never use leverage.**
3. **Be sincere with others and yourself. Don't deceive others, don't deceive yourself.**
4. **Do not boast about yourself.**
5. **Be diligent in everything.**

6. **Among any three people, there's always one who can be my teacher. Don't look for others' shortcomings; if you do, you'll find no friends. Look for others' merits; if you do, you'll find everyone is a friend.**
7. **Invest by spending 99% of your effort on research before investing money, and only 1% on buying and selling.**
8. **Do not envy or compare with others, as it makes life very tiring and leads to foolish decisions.**
9. **Think more when facing issues; your brain must not be lazy.**
10. **Do not be arrogant; the essence of arrogance is ignorance.**
11. **Don't play chess with bad players.**
12. **Actively connect with people you like.**
13. **Seek improvement internally. A gentleman seeks his own faults. Reflect on your own issues.**
14. **Listen more to others' thoughts, do not interrupt them while they speak.**
