hmm... I think I'm an easy going, laid back guy that's always in it for the laugh. Usually, the more sarcastic the laugh, the better. Even if its at my own expense... sometimes :). I try not to take myself too seriously and keep things in perspective. I think you should stay young at heart until you die.
This is not to say I don't have goals, ambition or drive. Values and integrity are big with me. I think you should have a code that you live by. I just don't wear it all on my sleeve. I put an emphasis on honesty and I'm happy to go the extra mile for someone that does the same.
