Just don't do it!!!

Your brain exists to serve you. Its dumb to let it take control of you. Just have some discipline!

Everytime I want to do something like eat junk food or smoke or masturbate, I just... dont. No technique involved. Just, dont! Its not that hard lol. Why do you want to do something thats inherintly bad for you? You are not your brain's servant, you are your OWN servant. Take control of your life.
