This may sound odd, or even cliche, but try practicing your lines. Practicing lines by the way, isn't about finding a cool pick up line, it's about how
you say your introduction. By that I mean, you can just practice saying "Hello, I saw you from across the room and thought I'd introduce myself. I'm....", or very simply "Hello. My name is..." or something similar and simple. Say it in many different ways until you find an introduction that is genuinely 'you' (whether that be friendly/warm/confident/cool/funny or other), and enough times that you become very comfortable with saying it.
You would be surprised how many guys voices crack saying something so simple to a beautiful stranger. 'Practising' saying this out loud does a number of things :
- It gives you an automated memory to fall back on
- it makes you more comfortable how you are going to introduce yourself
- you will know how your voice will sound (instead of being surprised to hear it squeak)
- you will come off as relaxed and confident (and if it doesn't work the first time that way...this is the good thin - just practice some more and you will become even more comfortable with the idea)
If practising lines sounds corny, just think of how many people practice their speeches when they are new to public speaking - it's exactly the same concept.
