I think it's a matter of probabilities. Yes, you can become rich, but your chance of achieving that is not very big at all.
Forex can make you rich, If not ask George Soros. The important thing is that you can take a loss and learn from it or stay at the 90/90/90 statistic, thats up to you.
If you can't maybe this isn't for you and thats ok, hope you find your path.
