…I was obsessed with my work — Bill Gates

Man, although I don’t recommend all-nighters, I do recommend being obsessed with your work—whatever it is. Not to the point of pulling all-nighters, but instead getting the best sleep possible so you can give even more energy, brain power and creativity to it.

If you’re not obsessed with your work, be brave enough to consider exactly why you are doing it, and whether that reason is sufficiently explains how you want to be spending your life.

NB: The review goes on to reveal that Bill no longer feels sleeping a lot is lazy.
