I have my own thing to check is that if I can stay away for a week and not login to the gambling sites means I am doing well. As well since I do not just run or play to only make money and more to just have more fun and make few friends worldwide and know them etc just helps so that you are not really addicted or cannot stay away from it. If I decide today for next week I would not be login and can manage to do that means nothing to worry for me.
This is another height of strong decipline. Having a strong control over your actions is a way of keeping your self in check and noticing if you are getting addicted or not. Staying a week without gambling a your own will is really a good checkmate for how much control you have over your passion and this if applied to other areas of life will give you a good life result.
