We use the expression 'excellence reflex' ... Doing something as well as you can do it and learning to do it even better tomorrow is a journey ... I'm not the least bit interested in perfection—it doesn't exist. It's a recipe to be pretty unhappy in life. I'm very, very interested, on the other hand, in the notion of excellence—and I do believe that excellence is a journey ... Excellence is honoring the work you did yesterday, all the mistakes and everything, you gave it your best, but dammit, figure out how you could do it a little bit better today.
