That's true, when we experience a tragedy or a mistake, we have to be able to stop complaining. Yes, it doesn't matter if you complain, but don't complain for too long because the longer you complain, the more you waste your time which you could have used for evaluation. Complaining is normal, but don't let it happen. changes your psychological to emotional so make sure not to complain at times when we fail to use it for something more valuable such as evaluation.
