Greed will always lead someone to ruin, I think it can happen in all things, not just in gambling. Gambling with a small budget will make you fine, there is no pressure after losing, life can go on as it should, so there is no neglected responsibility. Winning will be the only thing that brings pleasure in gambling, but it must be understood that it does not happen every day. I think experienced gamblers will understand it very well, self control not to exceed the limit is the main foundation when gambling.
Self control is like an important if not the most important element in a man's life when he is doing almost anything, a man with great self control has conquered himself nd cannot suffer addiction in gambling or every other aspect of live and so it is very important that as a gambler, learning to have that as a character is important so you do not suffer certain situations gambling.
Greed is another killer, that slowly kills those suffering it, they never get satisfied and always going all in such that they may get bankrupt at some point while chasing their losses or money generally. Winning in gambling brings both pleasure and also brings sometimes can bring about some tension, excitement and even emotional feel.
