I never set out to be a boss. If anything, my earliest and most basic ambition was to teach. Parts of management fit nicely with this inclination, but much of it cut against the grain of my impulses. I started out, for example, trying to motivate people through friendship, until I realized that didn’t work. Whatever I achieved came from constantly stepping back and reflecting on what I needed to do to succeed. I was a student of my craft because I had to be.
