Every gambler must learn how to have a control over their gambling habits, you don't have to let emotions or excitements to determine your actions. To achieve self control in gambling you need to have a responsible strategy and be disciplined to stick with it. I once read a book titled '7 habits of highly effective people' and the author emphasized that to be effective you need to be proactive instead of being reactive. Gamblers who let excitement to influence their decisions are reactive people while those that have a plan on how to react are proactive people. Have a budget for your gambling bankroll and stick to it, additionally it's best to let the amount be what you can afford to loose.
