I could not agree with that OP. Because it is hard and impossible to forget your mistakes when one day you experience big losses and in one day, you deeply feel regrets. Maybe this happens if you never gambled for many many years that even makes you forget how to gamble. But we are just talking about having some days for a gap which I believe every time were in gambling our mistakes will appear on our minds. Mistakes will never happen in our life again if we stop gambling but because we are still doing this, expect to experience it again and again. Our mistake here is we are chasing winnings and thinking we could win and beat the house always.
There's no way to forget how to gamble, you're just placing a bet, nothing else except you're playing table games. But after playing for few matches, I'm sure you will remember how to play it and the strategy you were use.
In order to avoid mistake due to gambling beyond your limit, you don't have to stop gamblng! just use the money you can afford to lose and never deposit more.
