Training emotions is not as easy as it sounds depending on the level of emotion that each person has, basically we are already aware of this, disciplining ourselves, setting initial limits and taking a break, all of these are forms of emotional management but sometimes at some point we ignore all of that and we forget the initial plan on the other hand at another point we can also succeed in following the initial plan in every game, for me this is normal in gambling because we cannot continue to stick to the initial plan, the most important thing is not to always fall into every session, and in any case, controlling emotions is an ongoing process so it takes time for us to be able to carry out healthy gambling.
Of course, it is always difficult to deal with emotion. However, it will be easier training emotion if we are aware of the negative impacts of uncontrolled emotion. Having stable emotion won't happen instantly, it should take times. I am sure if you always keep disciplined with your limitation both in the use of funds and time to spend in gambling, you can control your emotion gradually. The main point is you never try to recover your losses whenever you have bad time in gambling. When you reach the limit of your funds/time, you need to take a break immediately. Sure, we must always stick with our initial plan and the limitation of funds/time. This is the only way to keep gambling in a healthy way.
