Academe is full of potential geniuses who have never done a single thing they wanted to do because there were too many things that needed to be done first: the research projects, conference papers, books and articles — not one of them freely chosen: merely means to some practical end, a career rather than a calling…

If there is one conclusion to be drawn from the life of Leonardo, it is that procrastination reveals the things at which we are most gifted — the things we truly want to do. Procrastination is a calling away from something that we do against our desires toward something that we do for pleasure, in that joyful state of self-forgetful inspiration that we call genius.
