Every time you make a mistake, evaluation is really necessary because when you make a mistake that makes you lose, you have to be able to evaluate it, then take a break, don't trade, don't get emotional. What's more, revenge is enough for you to practice again, see what made you wrong, then evaluate it, so later you will find out what was wrong and you have to fix it because basically every mistake, if it is not evaluated, will continue to reduce and will continue to make you lose.
