I have always been an advocate of gambling solely for fun, cus with that mentality, we can gamble really with peace of mind regardless whether we win or not, but sometimes, it is just nice to stop beating about the bush and face reality, no body truly enjoys losing money, if it was so, casinos wouldn't have build their system in such a way that the gamblers are the ones on the losing side in the long term, but all the same, it all boils down to never allow the outcome of a gambling session decide your happiness or sadness - this is what i call discipline.
And when we can get pleasure from gambling at a trusted casino, we also have not to exceed the limit because that is the start of all the problems that happen to many gamblers. And if we see that the casino is changing slowly and not by what we knew when we first signed up, perhaps we need to move to another casino. Especially if there are already some problems that the casino hasn't been able to solve, it might be a sign that the casino will turn into a scam casino, even though that's not always the case.
