That's why it's important to learn from the mistakes made and learn how to do it responsibly.
While including me, I've learned from my mistakes and avoids those mistakes to be done again. Gambling responsibly is what we always tell to do for those that cannot control themselves and are facing gambling challenges. If they listen to the advices of other people concerning them, that's good but if they don't then it's better for them not to gamble at all or learn it on their own the harder way.
Otherwise, you shouldn't gamble, because it won't bring joy to you in the long run.
That's my opinion, of course.
I agree about that, if they can't contro lthemselves and keeps on doing those mistakes or any other new, they should stop. If they can't be responsible for their gambling actions, they'll have hard time dealing with it and can done much worse actions that they're never going to like. Eah of us have to deal with these consequences if we are already facing one, so, if someone is going to deal it on their own and they're on their right mind to face it then I think they're doing the right thing.
