We learn from our mistakes, that's what matters most and as we go further, we are more matured already to stay dicipline and only risk what we can afford to lose. Me as well, I have some bad times in gambling, I loss control and loss what I was not suppose to lose, but my journey will not end from that, blaming myself and learning is important, not other people or the other way around.
everyone will learn from experience because experience will make things better and more careful, and I practice self-control by taking deep breaths when ambition comes and trying to neutralize the situation to calm myself down when betting.
