Friend of friend we met was a big time chef up in New York, long hours, stress, regulations, junkie co-workers etc...he now does residential stuff, dinner parties, special events etc all in your own home. Loves it, maybe slightly less money but he says the joy of cooking has come back.
I worked kitchens in Glasgow whilst studying, proper restaurant but a brutal kitchen, i'd take preparing a meal for 1 at home at reasonable times of day for less money then that theater crowd in the west end lol.
