We need to practice since controlling your emotions is one of those factors that affecting our decision making, and we all know that a single mistake can cause a huge harm with your finances, if you know how to control then better to keep practising that kind of discipline it leads you to a enjoyable gaming/gambling.
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.
