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.
Many can't do that.
Those gamblers that have self control and can maintain themselves to keep checking if they're still okay or not. And if they can abstain from gambling within a week or two.
They have a good self control.
It needs practice and real discipline, let's be honest that it's one of the hardest thing to do, once we enjoy gambling we are forgetting about this especially when we are winning, we think that it's our day and we keep playing and playing until we lose. Player needs to know its limitation and starting to practice it from time to time is a great start in my opinion.
