We will not be able to escape from mistakes that we make ourselves even though we are confident in the accuracy of our system, but we must be able to be on guard when we lose, therefore it is very important that we correct every mistake that we make ourselves because in my opinion those mistakes are the beginning of destruction is if we are based on correcting it well, therefore, don't take every mistake with the wrong action, don't just leave it alone, but use the mistake to make improvements to each of you when carrying out analysis.
