It is quiet to see and I believe that all of us commit mistakes, a situation that also changes our gambling approach and behavior.
Of course, it is not in our mind and we try to avoid mistakes but still, it comes to us no matter what we do. But this thing sends us a message that every mistake we make has a positive result and one thing is that we improve and change our style to a better one. We could just think that we have to limit our gambling time, stop being greedy, and avoid addiction because we already know the outcomes as it happened to us in the past and we don't let it happen again.
Therefore, I would say that we don't have to be afraid of committing mistakes because this also helps us to see things that we need to change and become a responsible gambler.
