It is hard to realize greeds, especially when you can enjoy the game and win for some rounds because our mind will tempt us to play some more rounds. Greeds are what we need to eliminate or control because they can ruin our day in just one or two rounds. Maybe playing with a calm can reduce the tension that comes to us, especially if we win on some rounds.
Oh, do not forget to limit the money you used in gambling, not lose all of the money.
Greed and ignorance have always been a very dangerous combination but when you have those two characteristics and you are gambling out of control then this is a big problem, I do not know why people do not make a very small research before having dreams of becoming rich when they gamble, if they did so they will understand that their dreams are never going to come true and the best part is that they are going to save themselves the pains of losing money they cannot really afford to lose.
