Alcohol
It seems alcohol is the one thing I can count on to help me feel good about myself.
It turns out that if I cut myself off on work nights, drink water, eat throughout the night, etc - I do just fine in my menial construction job.
I can do whatever the hell I want on non-work nights. It ain't like I'll ever have a significant other, family, or really any real life friends at all. So I've found quasi-happiness in being a drunk - mind you, just a partial drunk.
