Making any mistakes as a tool for self-evaluation is indeed important. For example, if you make a mistake in opening a position, make it an evaluation so that you can practice using a good open position, such as waiting for momentum, waiting for a signal or so on. For example, if you place a stop loss incorrectly, then you have to be able to learn how to use the stop loss well, not too tight, not too close to your position, and you have to practice all of this continuously so that there are fewer mistakes you make.
