To answer your question, I do not have a control, when I start doing something I enjoy I do not stop. That is the reason that I do not gamble because I believe that prevention is better than cure. If I caught myself in the quicksand of gambling addiction, I have a plan. First thing that I should do is accept myself as addicted and tell my parents that I am addicted and they will help me in rehabilitating my addiction by cutting off the funds that I get from them and making sure that I always go home after school and blocking online gambling website in our Internet. I believe that if you can put your mind in to something then you can do it successfully.
Are you secured by your parents or are you consciously giving them your money? Then where are the guarantees that those pocket expenses that they will allocate to you will not go to gambling?
Such a strategy requires the development of strong willpower and awareness of their actions.
It's what you called trust. Parents always trust their kids no matter what, if their kids lies, it's not their fault anymore, it's their kid's fault for wasting their parents trust, and it's their guilt that will help them to realize and accept their mistakes that will lead to a life changing scenario, a positive one. Also, he admitted that he easily get addicted, that's a good sign of not getting into anything that is messed up like gambling addiction.
Another thing is his plan is really great, not like those gamblers out there whose plan is just to sit and enjoy themselves losing their money then blame it to other people.
