> For example I don't use an alarm clock on a day to day basis. I let myself sleep till I wake up. That works because I have no morning commitments or responsibilities and flexible work hours. It only works because of my context. Clearly it's useless advice to most people.

As someone who's 3 year old wakes up and dives into bed next to us somewhere around 6-7am. About 3 hours after the 2 month old has woken for a feed I'm very jealous!
