Let's face it, it's a painful art form...mostly, and thankfully. Why do I say that? On account of pain being a comedian's opportunity, whether it's yours or theirs.
Ever ask yourself why you pursue stand up comedy? You should.
Know your need to succeed....and to heal. Simply put, the more healthy you are the more you will look objectively at your material and dig in to the genuine funny images of pain, as well as the relief there of. So dig into yourself as well when you're mulling over your hastily scribbled twisted rants.
