I strongly agree with this statement. because indeed we will of course be easier in taking a lesson from a mistake. so then we know where we went wrong gap. and finally we will be more vigilant.
That mistake youre going to make there are people who already made that mistake and they already state out ways that we that are getting in new will be able to avoid those same mistakes too, or maybe to be able to reduce the impact of those experiences. All you have to do is take out your time and learn what those people did at that moment and also learn how they were able to avoid those same mistakes from repeating itself. You shouldnt wait till it happens to you before you start looking for ways to avoid it.
