I ignored learning about the market deeply and also I was greedy: I wanted quick money and tried to gamble. I tried over-trading and revenge-trading multiple times and didn’t understand the importance of risk management. I was impatient and not dedicated enough. These mistakes cost me a lot but I take all my losses as a lesson. The hardest part about trading, at least for me, is probably getting your emotions out of the way when you're trading. And I'm still trying to improve this.
