When do you stop? Do you have a daily limit or something?
When my budget plan limit reached the limit. Personally, i budget my money in many ways it includes my budget for gambling. I stop gambling when the minimum limit is reached, because in gambling if you don't set a limit your money will not be organized, which may result to money deficiency or money deficit or bankrupt.
Limit is the root of gambling, you can survive if you limit your money and time to gamble. Like a tree, a tree will survive if there are roots, and gambling, you will survive if you make a limit. Without limits, you can lose all your money because without a limit, your control will be messed up.
