Never underestimate every mistake you make. You must be able to evaluate what you did that caused you to fail, therefore every mistake makes an evaluation of yourself, whatever it is, whether it's technical, whether it's psychological, or management, all of that. You have to be able to evaluate when indeed you find a lot of failures there, so because you are a trader, you have to be detailed to see these mistakes that you have to fix immediately so that they don't interfere with your trading activities.
