If you read enough of those "day in the life" articles in newspapers about the daily routine of famous/successful people, you realise that they are probably complete fabrications. Even if it's not for competition purposes, convincing people that you do mad stuff like get up at 2am for a kale cleanse, followed by three hours of meditation is fun. And on top of that, it adds to the razzle-dazzle and gets people talking about you. That's why Michael Jackson pretended to sleep in an oxygen tent.
