I find it much easier to stop then when I am winning a game, I am the kind of gambler that wants to enjoy my winnings by having a drinks or celebration, although I also have control when I am losing but stopping when winning is the hardest thing for me.
There is one small error in your strategy. You exit the game when you reach a certain result. However, when you win gambling it can be
due to your luck or because you are really good at the moment, your concentration is on top and you make the right decisions.
If you play well, your concentration is at its peak, it is in your interests to spend as much time as possible in the game in this state in order to maximize your profits and to some extent minimize the risks associated with a bad game in less concentrated emotional states.
Leaving the game ahead of time you lose some advantage in the framework of your game over a long distance.
