Actually we do not need an excuse to stop gambling. Gambling is not a very good thing to always do, but as long as we can control ourselves during gambling, we can get away from bad things. But the decision to stop gambling is a decision that must be respected without having to question why.
maybe for some of us, the excuse is when we loss all of our money then we need to stop it and we are really stop from playing gambling. but I don't think that we are stop for a long time because, for the gambler, there will be a time for them to come back to the gambling place and continue for playing gambling. but if we are know that playing gambling cannot give any money then we don't have to play gambling for all day and it is better to stay away from gambling games.
