I decided to systematically compare my performance in that one specific category of my life—work—with my performance in the other important life categories, and to give them all equal importance. My mind has always worked systematically to begin with. For example, I still operate according to the school-year calendar, where September heralds a new start and May/June the conclusion of another grade; as I write this, in the spring of 2014, I am finishing up what I think of as Grade 59.
