The higher power is the substance, be it booze, heroin, coke, meth or dopamine (for gamblers and others)

Accepting that that chemical will always be there, always call to you, always be there to make you feel good when everything else isn't working is the point

Surrendering to the fact that it's forever in your life, no matter what you do is the point, not surrendering control over your actions

I know what I am. I know how the things that I do shape my life in every possible way

It's about how I manage it, not ignore it or pass the buck
