And this very feeling of regret that the player took the wrong steps in a gambling game and because of this lost, unfortunately, spins in the head of such a player for some time until he forgets about his unsuccessful game. I think that perhaps such obsessive thoughts are an unpleasant consequence of gambling in cases where the player is focused on winning as the most important goal of the game.
But if the approach to the game is different, that is, simply as a pleasant emotional way of spending your free time, then such thoughts do not spin in your head for long and do not cause practically any unpleasant sensations.
Of course, the feeling of regret is so deep that when the gambler has lost a lot of money due to their bad behavior, they will think too deeply and the consequence is that if they are unable to withstand the burden of these thoughts, they will experience severe depression.
It is true that if a gambler uses gambling games just for entertainment then he will get pleasure and enjoy every game he plays because he only uses gambling when he needs it, not to make money in addition, money might be played excessively.
Regret should be related to its action as "learn", because in gambling, you can't regret all the time without learning. Remember that what we are risking is money and it has to be taken care of the best we can do. Our betting strategies can be build overtime, it's expected that we will improve as we learn but the lack of control that is still happening from time to time is a big risk that will destroy everything we work for.
We should be a discipline gambler and the rest will follow.
