Aim higher than being a bar-back.
This is not to disparage that job, or those who do it. This is about you. There is a theme in your posts, about realizing that drugs and drink have kept you from your potential, feeling sad about your wasted life, and wanting to rebuild it.
You want to rebuild your life? Get clean and sober, set high but achievable goals, then accomplish them. You'll likely start at the bottom of the ladder, but pick a ladder with more than one rung.
