Good point, as there are gamblers who have that same mentality, instead of taking a pause and re-assess what they did wrong they continue to push forward, and most of the time they ended up losing more as they think that for trying to add deposit to their wallet they will have that luck and recover their losses, that's the reason why practice and discipline needs to work together with a common aim, minimizing losses and not to let emotions to dominate inside.
Yes, emotions always present such a problem. If you let them take control of you, they will dictate terms that in most cases lead to disastrous results. Therefore, a player needs to learn to control them, and not only their negative manifestations, but also positive ones, because excessive enthusiasm can also play a cruel trick during the game.
When it comes to gambling or other decisions, you cannot rely on your emotions, but you have to make a decision based on your skills and strategies. Gambling is generally considered the riskiest game, so if any decision is made without sufficient knowledge or without applying your skills, then that decision will be wrong, which will result in the gambler losing a lot of money. What I mean is that everyone can gamble, but not everyone knows when to stop. So first, you have to make a habit of taking a break in between gambling and also consider yourself a responsible person. When a gambler considers himself a responsible person and when he can stop in the middle of gambling, his control over gambling will come automatically.
Such control is difficult to execute but it's doable if you practice it each time you gamble, and like what you have said if you can make that hard stop in the middle of your session meaning that the control over your emotion is far better than your lust and desire to gamble, it's really tough competing against your own will, but being responsible means you need to set aside your emotion, it will give that decision to make sure that you are in-control and you are good whatever might be the outcome of your gambling session.
