You must understand the type of game you are involve and you always need to have that hard stop to make sure that you are in the right track when dealing with your decision making.
Well, personally, I also say that things are very different when you're playing. There are always many things on our minds while we're playing, especially winning. But when we're winning, we believe that we deserve to keep winning, and that's the big mistake. That's where we have to stop.
It may be that when we're winning , it's only a small amount of money, but if it's enough to withdraw, then we have to do it. There's no other way, because it's better to withdraw it than to lose it, and understanding that is very difficult.
No one deserves to win forever. The sweet thing about gambling is that it doesn't recognize any title, influencer, or people of higher authority when you predict wrong then the bet is bound to be lost. It is no respecter of any man and that should get into the mind of every gambler. Because a gambler was lucky to win often or straight in a row without experiencing any loss. That doesn't mean he has immunity to losing in gambling.
No money can be considered little when we win. Just like you have said once the win is up to the withdrawal amount then it is good we withdraw the profits. Even if there are chances that we could still win if chase more wins but we should prepared to not feel regret if lose it at the end.
