Being aware of this it's not going to be hard to control our emotions if we have discipline. As long as we're playing in moderation and able to stop when already needed, then you can prevent becoming an addicted gambler since you know your limit and not greedy to win. Past experiences can help to accept the situation if we happen to lose again.
Discipline is the best weapon against emotions, as long as it is accompanied by good and clear risk management with our money, On a personal level, we should always consider that the most common things sometimes turn out to be more complicated. It is clear that emotions are not extremely difficult to control, but there are other things that we should take advantage of to control everything , and that is money together with discipline.
The problem is that, not that many gamblers have discipline, and if they have, they aren't applying it into gambling or they can't control themselves especially when they're losing money.
Proper risk management is the key when it comes to gambling. Setting a specific amount of money that you will be using for gambling, and sticking on it even when you lose your money is one sign that you have discipline, and self control. We've seen gamblers losing significant amounts of money because they don't know when to stop when needed, and they don't care about the risks as long as they're gambling. Self-control, and discipline are the 2 hardest things to achieve when it comes to gambling, but learning how to have them both and apply it on gambling, you're part of the top 1% of gamblers already.

Overall, discipline and self-control is a must have not only when we are gambling, but in everyday lives as well. We must learn how to have both of them.
