You have the power as a human being to choose to believe in anything, that includes the choice to believe in yourself. If you believe in yourself, in your power, you can transcend old habits and never go back. I found that if I looked clearly at what alcohol did to me, I could see beyond its momentary pleasure, to all the far reaching negatives, and it seemed the only sane choice to quit and never drink again. Getting through the first weeks, couple of months of lingering withdrawal is a chore, but you choose to warrior on, not be a victim of the addictive beast. Then you have a life in which you have the energy to make positive use of the moment you are in. Victims can't do it, warriors can.
