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.
