I agree that it will haunt you for hours or maybe even for a day, but I don't think it will haunt you forever unless it's a very big win that you are unable to withdraw.

It's a problem with most gamblers, and I won't be a hypocrite to say I didn't have that kind of attitude. I did. It's not easy to be satisfied when you hit a win, especially if it's not enough or it doesn't hit your planned winning amount.
If it's a big win, better withdraw a big portion out first and just keep playing afterward. That way, we won't be spending too much, and we will have time to think twice if we will deposit again after we deplete the remaining balance that we left after the withdrawal.
