Usually setting a goal is a good idea. If you want to win a certain amount, or just double your amount. Once you reach your goal, or even close to it, then it's time to stop. Cash out and withdraw!!
It is, but when you win so much money from gambling, it will hard to stop because people always greedy and want win more. And i also very2 greedy. Once i have a target but when my target reached, i always go more because want win more.
I totally agree with you both, but it depends on the gambler mentality , I am doing gambling but my target is get double or zero, if i achieve my double i quit and withdraw it next day start fresh, even if i lose it i will quit as i set the bankroll what i will play win or lose no change. so at the end of the day i am in profit. This is all about ones thinking power.
