1. The biggest scam in investing is making you believe you can get rich overnight.

2. Don't ask what to buy; first ask if you can afford the loss.

3. When everyone is talking about opportunities, it's often the biggest risk.

4. Experts are waiting for opportunities; ordinary people are always chasing rallies.

5. Those who make quick money usually lose it back at an even faster pace.

6. The market cures all kinds of arrogance and harvests all kinds of greed.

7. What you think is investing is actually just giving your money away.

8. Control your emotions, and you can control your wealth.

9. If you can't understand the market movement, treat it as a scam.

10. Real money-making is never crowded.

11. Following the crowd is instinct; independent thinking is a skill.

12. Bull markets breed gamblers; bear markets filter out the strong.

13. Don't use luck to challenge someone else's professional skill.

14. Investing isn't about who makes the most; it's about who lasts the longest.

15. Keep your composure, and you've already beaten 80% of people.
