In trading, if you're doing well, you haven't gone live, there's no need to trade uncertain ranges or sectors you're not good at, you've experienced a 20x account increase, then a drawdown back to only the principal, and now you're back to 5x.

So I now tell myself:
1. Only trade sectors I'm good at
2. Summarize and improve my trading system
3. Don't look at profit and loss money, only focus on your entry points
4. Don't trade what you don't understand
5. Never hold a full position!
6. Accept losses
