this is why we need good management in managing our gambling habits. every day I always start playing with a small capital under $ 10, if I lose then I will stop but if I win then I will continue until I can withdraw my profit and still leave the capital in the account.
the point is don't be too curious about gambling, play again tomorrow if you lose today but take profits if you win today, do that habit then I'm sure your winning percentage will be much higher than your loss.
You are right that money management is the main key to be safe on gambling. But usually maximum people cant manage that also, I cant do that. When I loss 10$ I try to bet by 20$ and if loss then try to bet by 40$ in this way I loss again and again. But if I make profit then I become afraid if I loss that winning. So, my winning cant be higher and my loss become higher than my winnings.
I'm also not always able to control myself, it's just that I try to keep a cool head when I lose or win when I gamble. the logic is simple, if I lose $10 and then stop to continue tomorrow then I only lose $10 but if I continue to gamble, my percentage of being able to reverse my initial loss is only 40% then it's better to continue playing tomorrow than forcing myself, money management is an amazing trick.
