Michael Jackson "Work and Soul" (part 1 of 4); the whole series gives excellent perspective. My takeaway (and there are many others):
The perseverance, repetition of routines, employment of technological innovation, and commanding team leadership he exhibits are components of a work ethic distilled from a life spent in studios and on the road, making and living some of the best music the world has ever hummed. Such an ethic provides priceless lessons in the kind of self-discipline that any creative artist must accomplish in order to sustain a career moving forward from one peak achievement to another.
NOTE Can't remember where I ran across this today, or I'd give a hat tip.
