I think you should stop gambling when you're feeling not good in it. Keep chasing the loss is the worst thing in this life.
We stop when we lose, that's how we deal with gambling but it's necessary that we will not lose that much.
Gambling is fun but it needs to risk our money in order to play it, therefore you need to have the discipline to be able to enjoy and be safe.
When you are not feeling good then just stop, there's still tomorrow and casinos won'g go anywhere.
In my opinion you couldn't always win with the things that includes risk because having that chance with the that helps you realize that it's not that easy to win. Gambling requires money and if you don't have that security in yourself then you shouldn't really go for it because it's going to eat your money. I agree that you should be disciplined.
