“I can tell you that the comfort zone has many upsides. It may be associated with sloth and cowardice and any number of paralyzing, irrational phobias. It may be a dark abyss where misunderstood people lie around in fading recliners listening to outdated music. But I’m convinced that, when handled responsibly, the comfort zone can be as useful and productive as a well-oiled industrial zone. I am convinced that excellence comes not from overcoming limitations but from embracing them. At least that’s what I’d say if I were delivering a TED Talk. I’d never say such a douchy thing in private conversation.”
