At AT&T, I learned an awful lot about people, and how important it is to have the right people in the right jobs. And when I say 'right people,' I'm not talking about their college degree or work history; I'm talking about things like bearing - How does this person interact with other people? Can he or she talk to you and not tick you off?
Find your passion is in life, and do what you can to integrate that into your work life. That's not to say you won't have occasional frustrations in your job - that just goes with the territory - but at least you'll feel better inside, and that, over time, will mean more to you than you might think.
