It would be someone who can display good communication skills, wit and a demonstrable intelligence. Someone who puts effort in their appearance, but not vanity. Confidence, but not douchebaggery. Likable, but not a suck up.
..and it helps if they are accomplished in their life.
Love the word, 'douchebaggery' that should surely make it into the next edition of the dictionaries :) I hate suck-ups too - maybe that's why I will never get a promotion :P
Lots of new ones in there - I hadn't thought of compassion, for instance - and yet that's very, very important to me. I struggle with those who are cruel and uncaring to others.
