I am a pretty laid back guy. I consider myself to be intelligent with a good sense of humor. And while I am ambitious and consider my career to be very important to me, I don't take myself too seriously and can laugh at myself...and there are plenty of opportunities for that!
I would describe a good match for me as someone who is fun, intelligent, articulate and has a good sense of humor. Someone who likes to go out and have a good time on the weekends (maybe in Vegas even), but can also relax and be mellow once in awhile with a bottle of wine and a movie at home.
