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.
From the topic balone, it has different ends.
1) Your mistakes towards gamble might make you to regret ever knowing what gamble is or knowing the word gamble. There some mistakes that it not ment to be made because it can ruin one's life.
2) Your mistake might lead to your success, most mistakes that led to our success are very rare. It doesn't come the way we expects it. However, since it's called mistakes it also means that we won't know when we are doing them.
Although everyone can not prevent themselves from making mistakes but we all try our best most time but since we are humans. That's why we make mistakes most times, even when we are doing things in a careful way.
Obviously, most times when we make mistakes and the mistakes leads to our success in gamble, most people hides their own because they believe that it's their luck. IMO mistakes are mistakes one can't hide it, mostly when it's some negative or positive. However, you winning through your mistakes if still your luck.
