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.
This is similar to what I said before now still on this matter, everyone have their choice for what they want to do with their money. Some people have multiple sources of income and the 10% of their monthly revenge could be $500-$1k, if such people are gambling with such huge amount, no body should judge them or see it as a financial mistake because the person can still get that money back in a short period of time. Some people that can be said to be making financial mistake are those gambling with all their income.
