For me, winning isn't just about withdrawing your money from an online casino it's also about having control over the money you use for gambling and over yourself. Sometimes, you might be able to withdraw your winnings, but if you end up depositing it back into another online casino because you lack control, you're not truly winning (Based on my own experience). That's why I believe you're real winner when you can control your gambling habits.
True because not everyone that withdraw their money use it wisely therefore I think too that how we spend our wins from gambling is the real winning but before we can spend it, it has to be withdrawn. People would do not withdraw but continue gambling is making a mistake because a time will come when you can not control yourself and you will use the money that is in your account to gamble. Real winners know how to use their money for things that will make them rich and not for things that will not be useful to them. Many gamblers that I know off and those that I read about are always very wasteful with their money and they return back broke after a short time therefore after withdrawing your money, we have to make good use of them just as you have said or we did not really win anything.
Enjoy the moment when you manage to quit while you still your winning profits, you should be wiser when taking care of your benefits, as you both mentioned most of the time those gamblers who have that chance to win missed the opportunity since instead of quitting they push forward and then lose everything back or some manage to stop but deposit their money again in hope that they can easily repeat the same outcome with the winning streaks that they experienced from the last sessions that they've play, a misconception that mostly cause losing your money back to casino house.
