You don't get anywhere in comedy for being perfect. You get somewhere by recognizing you're not perfect, and set about putting all those imperfections under the comedy microscope. Run them through the ol' comedy lab.
What does that mean?
It means you begin to break down life's hurts, embarrassments, weirdness, to little scenes that can be talked about and/or relived in short emotional performance bursts. The goal being to gain laughter as you release tension on each sharing.
What's to be afraid of? The words will come, just feed your imagination some images and never fear to feel. Then put words to that.
Comedy is big on how things make you feel.
(from family, to commercials, your job, love life, fears and on and on...)
I mean if you want to get noticed you have to remove yourself from doing comedy and get into doing YOUR comedy.
How do you do that? Get to figuring out who you are. Get to know yourself. Ask yourself some hard questions and ask the question... why,... a lot.
Why do you do certain things? Etc. etc.
Stand up is an art form that you can make all about you. It's what you want isn't it? Dare to risk they won't like you. They will, you'll find a way if you're truly meant to do this crazy thing.
That's what you want to know as well isn't it? Are you truly a comedian? If you are stick it out there kids!
Risk and reap!
