Solution to this problem is to properly learn to manage your bankroll. Completely stop when you already have enough gambling. This way you can gamble with more freedom without thinking to secure your capital first before you play.
Well for me the key to everything is in that, knowing how to manage the money, I personally according to my experience in the casinos and for so many things that I have been through that I learned that anything I win in the casino no matter how little it is I have to withdraw it and see that money in my hands, either to spend it on whatever, but spend it, not leave anything in the casino or to play, after I spend everything, if I want to play what I should do is a new and small deposit and play with that, and that will always be my advice.
