If self inclusion like you called it is what will work for a person not to be a gambling addict then let him do it, it's better to exclude yourself from something that you think is harmful to you. But you didn't have to exclude yourself from gambling inorder not to become addicted to it, if you're able to practice responsible gambling and be disciplined to stick to it then you can gamble and not be addicted. To me responsible gambling basically means to gamble with the amount that you can afford to loose and don't chase loses, to achieve this you need to have a budget for your gambling. If you don't see gambling as a get rich quick scheme then I don't think that you will worry much about hitting the jackpot because it might never happen.
