One feeling I've discovered over the years is, when you're winning, greed steps in and you don't feel like stopping and immediately you start loosing the thought of recovering all the little that has been lost so you can quit will hit your mind and even though you recover back you still feel like gambling more but in most cases immediately you start losing you just end up losing with few wins until everything is exhausted. As if this is not enough it will still repeat itself in the next gambling session.
So the question is, why don't you quit when you've won quite a reasonable amount? Or when you've evened back your previous max win?
Money itself is a temptation, especially when you don't have to work hard to earn it. When you have to earn money, temptation basically doesn't work. However, the temptation to earn money is not only in gambling, but if you show someone a pile of money and let him take it freely, he will collect an amount of money that he is not able to carry, in this case if there are strict rules, he will lose all the money but still collect an amount that he is unable to carry. Basically, this is the temptation, even after we win in gambling, our greed does not end, we keep chasing after more money, in the end we have to lose everything.
