Last summer I went to Chicago for training with a voice coach from LA. He was hilarious, gave great insight and was worth every penny.  About midway through our session, I was going through a script, a little voiceover spot for a major retailer, and as I got ready to record, the easy, free-flowing way I spoke turned awkward and halted.  Inside my head sounded like this: Do I seem like an actor?  Am I remembering my technique?  Am I smiling on my inhale?  He stopped me, gave me some pointers and we tried again, but lo and behold, I was awkward and over-rehearsed once more.  Am I relaxing my tongue?  I'm reading copy for the role of a mom, do I sound like a mom? Do I want to sound like a mom?  Maybe if I succeed at this, I will book a big job and then I won't feel like such a phony.  As he stopped me, he said, "You have to stop trying so hard to control it, and just let it be."
