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.
