I can remember Mohammed Ali being interviewed and asked if he was "proud" of being the best boxer in the world. He replied that he was, but he'd have been equally proud of being the best bin-man in the world.
Being "proud" of your job has got nothing to do with what the job is but EVERYTHING to do with how you do it.
If you're actually talking about a job that makes you feel good or attracts the envy of blokes down the pub..................that's something different, but it's not "pride in the job"
