I only set an amount of money when gambling. This way I can manage risk while gambling. I always have my emotions in check whenever gambling and take several pauses or breaks in between gambling to freshen up and to avoid being greedy. I also set an amount where I will stop gambling once I win an "x" amount. This way I can control my greed. Whenever you I am in a losing streak I never trust my guts that the next round will be a win, I stop briefly. There are a lot of things we can do to handle losses, however, emotion is one of our greatest enemies when gambling. We get carried away, we cannot think straight because of emotion.
Discipline is the most important because in this way we can at least control some big risks, especially in the budget that has been set, while managing emotions is still a bit of an obstacle for everyone including me but I always refresh my mind so that emotions don't become too much even though it is the biggest enemy of gambling.
I admit that now I can control the budget, accept the risk of losing the game, don't get emotional, and there are limits that must be done so as not to overdo it when we are losing at gambling.
