I remember reading once about some famous person(s) who had attended some type of dinner party. About one man, she said "He was the most fascinating person in the room." About a second man, she said, "He made ME feel like I was the MOST FASCINATING PERSON in the room."
You want to be the second type. Find out about your date; ask them questions to draw them out, then add observations or similar experiences. Be more interested in them, than in talking about yourself.
Tips for an AS person though; make sure your questions feel like a conversation, not an interrogation! So, slowly ask and try to gauge their willingness to talk about themselves.
If they ask you about yourself, (and they should) keep your answers truthful, not *too* personal (yet), and avoid a long monologue.
To me, the best dates are where there is some activity to focus on, not just sitting in a coffee shop trying to make sparkling conversation. Even something as simple as going for a walk or meeting a zoo, for example, will give you a chance to get to know each other without too much pressure.
Just remember, they're nervous too!
I like to think I know of which I speak, because I'm probably old enough to be your mother, but I'm definitely NOT your mother.
Good luck!
