Why creative burnout is caused by job resentment, not too much work

I’m cofounder of a creative agency and an ad man who's been in the field more than 30 years. But I am also a martial artist with multiple black belts, a novelist of 12 years and a father and husband who has lived in four cities and in two countries. How do I do all of that? The answer is in the question itself: I have been able to do all of that because I do all of that.
