The only thing you should concern yourself with is the individual performance. Stop reading success stories of others if they make you feel sad. If you bought at $8000 and was able to sell at $8500 then it's perfectly ok! You shouldn't concern yourself that price has risen to $9000 or $10000 after that. If you made profit, in short, you made a successful trade.
what do you mean individual performance?
is that some kind of hard work?
controlling emotions in trading is only a matter of time, if we already understand trading management and always practice it, just wait for your emotions to be controlled, because controlling emotions is like planting a tree, if you want to feel the fruit then you have to be patient.
