As long as we can learn and practice self control in many activities, we will get used to it and will not have difficulty to used self control in gambling. We can prevents the big lose while we also not deposit more money because we understand that can leads us to keeps playing gambling. We needs to be wise depositing the money for playing gambling as we have a reason to stay away from the big lose. Yes, deposit only the amount that we can afford to lose is the recommendation for every gambler so they will not break their rules to control their gambling activity.
I think having discipline in betting is more important than actual win or loss in betting. One cannot always win betting but when if one is doing responsible gambling, he will surely not lose his capital.
One idea can be to deposit less in betting site, so that you are not tempted to put more money in the bet, that you initially thought about. Risk management needed to be follow, no matter how it is followed.
If you can always stick to your rule by always limiting the money in gambling, you will not experiences the lose that can be bigger. You will have a chance to enjoy the games while you don't thinks much of the wins as the wins is not your target when you playing gambling but you only wants to have fun.
I don't think people bet for FUN. They bet in order to make money but only if they can realize the importance of risking how much money and focus of less risk per bet, this could lead to more stable gambling income. People try to over spend in gambling because they want to become rich overnight. Getting rich schemes will only make you lose more money.
Patience is still a key factor in many activities including gambling.
