but for we gamblers, we are fighting not to lose too much as soon as we start gambling.
I was attracted by your last phrase. Tell me how to fight against losing money in a casino. If everything depends on the player, how much he spends, when he stops, and how much control he has over himself? What other fight can there be? There is only one result: if you don’t want losses, don’t play. Accept loss as a normal occurrence, and victory as a unique event. No other way. I don’t believe those who say that they know that they are good at some games and that they will come out a winner if they play for a long time. All these myths are easily debunked when you force a person to prove their skills.

I guess he means as in any war the most difficult fight is the fight with yourself and I think that is what maybe he is referring in that phrase there. It is easy to know the theory and the theory that chances are very slim for any gambler to win is well known to any of them though the adrenaline and dopamine anyone feels while gambling makes you easily forget about what happens when you don't stop, unfortunately most people release this only after they have finished their session as during the session they are deceived by adrenaline, dopamine or even devil's whisperer that you are going to win this time. If I accept loss as a normal occurrence and victory as unique I am not dumb enough to continue gambling and this must be the reason also why most gamblers keep going, they don't see it that way.
