I've tried to restrain myself from gambling when I had money in the form of a balance. I've played games or watched movies and videos, but the desire to win has caused me to lose control, ultimately depositing my balance at an online casino and starting to gamble. I've experienced this myself, so it's difficult to be a responsible gambler unless we force ourselves. You're right, we must be careful when gambling, because the decision is ultimately ours.
Having the desire to win isn't bad but at the same time knowing fully well that no matter how we desire to win, losing can also be coming your way, that's the real thing, man you're just facing the reality in gambling, please don't lose control, just retrace your step, it might not be easy at this moment but you can actually do it because you own your self control, you decide what you do, don't allow those instincts that keep telling you that when you keep trying, you'll win, be a responsible gambling by controlling those urge that keep coming your way.
No doubt dude, being a responsible gambler is not a play, one has to be very desciplined to do this but we can actually do it, it only requires we saying this is what we want and sticking to it.
