Limiting the time means limiting how many hours you gamble and see how much money in your account, so when you see your money is not increasing instead reduce, that will be the time to stop gamble and leave the place. That means you should control yourself and avoid the big risk that you can get from gambling. Maybe when you can enjoy the game, that will not be easy to leave, but you must do that if you do not want to lose more money.
When you have decided to gamble, you're already taking a big risk and you have to realize that before you gamble. Enjoying is always the excuse that we can use but we don't know how long we can take that excuse for ourselves if there's no good effect anymore and most of the results are not that good enough. Your money control lies on ourselves and there will be no other people that are going to do that for us even though we cannot dictate our fates.
Most gamblers do not know the effect, especially if they have already been gambling for a long time. What they can feel is only enjoying the game and that makes them hard to stop the game. If they continue playing gambling without realizing how much money they already use, that will be only a matter of time for them to lose more money. The risk behind gambling will be bigger, and most gamblers still do not care about that instead of continuing to play gambling. They will realize the risk when they lose all of their money, but that will be too late for them.
Yeah, most of the gamblers nowadays don't know the risk of what they're entering that's why they aren't concerned about what will be the outcome of no control gambling. At first, they just want to be entertained in gambling and after that, they're getting compulsive or addicted to gambling. They will only realize those mistakes after the lose they're experiencing and the negative effect of it in their lives.
