Elon Musk announced that he sleeps on hard ground to sleep well.
Elon Musk explained how he sleeps quality in his statement on Twitter. So is this medically correct?
Goodnight X. I’m sitting here on the floor of the SpaceX rocket factory in my jammies before bed reflecting on the week. The central lesson of this week for me is to never let yourself slip. Mediocrity is knocking on your door at all times and it must be constantly and forcefully beaten back. Early in the week, I made the mistake of sleeping on a bean bag on the rocket factory floor. I did this for several nights in a row. I’ll admit, it felt good. I could feel the impact of such luxurious sleeping conditions seeping into my soul. I was losing my edge and becoming weak. Midweek, I got it together and returned to sleeping on the cold, hard floor with nothing but my pajamas on. From that point on, my entire week turned around. I started firing on all cylinders. This is a good reminder that you need to immediately course correct when you feel yourself slipping into the warm embrace of mediocrity.
