You cant make him straighten out. there is no way. You cant control anyone but yourself. He will only change if and when he wants to and that is usually after we back off. Thats why you are getting advice to take care of the only person on earth you can change...yourself. There is no magic that will make your grandson do well. As long as he knows you will house him, save him and support him, he has no incentive to change either.
it has to come from him and it will only come from him and probably only if living a useless life is harder for him than its been.
