The most important thing is to make sure that you manage your risks...I'm saying this because as long as you are a constant gambler the chances of being in profit at the long run is low, that's why you should always take advantage of the profits you make and cut down your stakes, these are systems that can maximize profits and minimize losses..if this isn't done the casino would always have the upper hand
The problem with many gamblers when they're on the winning side, they're not taking their profits and instead of minimizing the bets they do, they're betting more.
Because of having those moments that they're putting so much confidence on themselves, make them not quit and not take their profits.
All it takes is to become a disciplined gambler and you can claim all you want that you've won against the casino and made yourself a satisfying profits against them.
