'the growth and satisfaction which comes from developing your skills and enhancing your career'
This puzzles me - do career-oriented people genuinely think this is something everyone feels? I am not rich by any stretch of the imagination and have worked since I was 17, in a variety of jobs, and have never felt any satisfaction nor enjoyed a feeling of personal growth from developing my skills and enhancing my career. I have constantly felt a sense of exhaustion, boredom, stress, desperation and deep desire not to have to do this shite any more.
That's not to say I don't want to contribute to the world - I volunteer, do some activism and am part of some groups, etc. Paid work ain't where everyone finds their joy.
