Personally I had a set target both when winning or losing I quit, however before I reached that conclusion it took me a while to achieve it,
It's good you where able to set a target and stick to it, not everyone has such trait, it takes discipline to do such because when someone who's benefiting from a particular thing no matter how risky it is, if they don't have self control, they could get carried away by the benefits they're getting from it and gradually become addicts, however the major thing that makes it difficult for people to quit even while they're having much losing streaks is lose chasing, but if someone is not very wealthy enough to afford such habit they could gradually quit. Well in conclusion, it takes discipline for people that fall under such categories whether people with much or less winking streaks to avoid gambling addiction and that's just it.
It might be a plan of qiut at a tatget point or winning after a target amount. But the target must be break after reached the target and it will be higher than the initial target and once again will break when it reach and it will be higher again and that will be reach but will be brocken once again and it will continue like this way.
