One of the most unhappy goris I know is a girl who has either been in relationships where she gets severely abused and then dumped by some master-of-the-universe type with a big job and a crummy character, or goes out with some very sweet, good-hearted guy whose paycheck or job somehow indicates to her that he's not 'ambitious' enough, and she dumps him and breaks his heart. She's well-educated and very, very physically attractive but just turned 36 with no real prospects for marriage/family anytime soon. She can't get it through her head that not being on your blackberry 24/7 does not mean you're a loser unworthy of respect.
Good character has nothing to do with your profession. And good character is what you should look for/respect/look up to in a man.
As for profession, is he a hard worker? Is he committed to playing the role of breadwinner? Will he be able to provide a reasonable standard of living for his family? Is he able to keep you intellectually engaged? If the answers are all yes, screw the details---he's a keeper. :)
