Quit drinking first and commit yourself to sobriety for good, and then start picking lint out of your belly button. Or not. If you think you need to do some other stuff to set your life right, by all means pursue that. But you won't be able to do that until the alcohol bit is cleared away and straightened out.
In some ways, setting your life right is what living your life can be. Exercise, mastery, friends, love and hope, spiritual growth and pursuit of knowledge, all of these things can be setting your life right, and growing in your sense of self while you do it.
But you can't drink until this is achieved, and that's because you can't achieve anything while drunk, and because these things cannot be completed, only sought.
So quit drinking already and get on with it. Time's a wasting already. Onward!
