Maverick,
Nice name by the way, I'm a Top Gun lover myself. Even have a TopGun shirt that says "ICEMAN" on the back.

Anyways, I can understand you are nervous. Please understand this isn't like a test where you can cram before you go out. It just doesn't work that way. What's already in your automated response is in there.
Be ready to fail! One of my favorite quotes of all time from my career in sales is "Your willingness to fail, directly affects your willingness to succeed!" You're going to goof up in field. I'm sorry but its going to happen. I'm pretty good at this after 6 months, but I still screw up. I've faced that its going to happen, and when it does I shrug it off.
I'm not saying you can't get a phone number in ten minutes but try to go out with the expectations of having fun.
