The best choice has always not been taken by many gamblers when they are in green not until when they start getting series of reds with each bet going further that's when they get back to their senses to wishing they had thought about quitting while they still had so much in hand to leave with. Insatiate behaviour is an enemy every gambler should deal with, if not, they will always lose all after any little win.
That's what always happens, it's happened to me, to understand that one must stop is when experience says it, it emphasizes it, because money must be taken care of and when you earn it you have to value it, it's luck in the end, but to get that luck there had to be a previous effort, even if the effort was very minimal, those things must be valued.
