Enthusiasm and honesty go a long way. The most important trait to exhibit would be confidence. Luckily, creating confidence is easy, you just fake it until it catches on. Sure, you can read more in-depth articles about "finding things you like about yourself" and "positive mantras", but if you just go out intending to appear confident, you will in fact become confident. I pay a lot of attention to the way that people speak. If you stutter and say "um" or "uh" a lot, you will sound unimpressive regardless of the topic. The other comments in this thread have the books nailed down. "How to win friends and influence people" and "Influence" are largely considered the best books on the topic. I'm very interested in body language which is very related. If you force yourself to stand confidently, you'll feel it as well the others around you. I found "What Every BODY is Saying" a lot of fun although it's not quite as full of information.
