There is a pretty well known speaker who wrote about his first public speech. He was to record himself, and it would listened to by some 5,000 people. He spent hours and hours re-recording himself, until a older friend stopped by and laughed at him, as follows:
"You are being nervous because you think that you might not be perfect, and doubt creates a feeling of nervousness and unsurety.
Well, I can dispel the doubt. You won't be perfect. In fact, you will be pretty lousy, because it is your first time, and it it is in front of a relatively large crowd.
So two pieces of good news. You needn't be nervous. And its not so bad that it will go lousy. Because everyone knows it is your first time, anyway, and they are expecting you to mess up. And this way, in the future, you will actually be great!"

A lot of wisdom there, IMHO
