5 important lessons I took a long time to learn and that cost me a lot; if I had started today knowing them, I would have saved myself many losses, and the path to success would have been faster:
1) Never stop studying.
2) Never leave the plan.
3) Never underestimate the market.
4) Never overtrade.
5) Never forget that the main goal is not to win in every trade, but to lose less than you win.
