Excellence

Two quotes on excellence, the first I relate to (the debilitating part), the second, healthier quote, I aspire to:

"But being [excellent] is also about having an insecurity that is almost-but not quite-debilitating. The best people have trouble living in their own skin, because nothing is ever great enough." - David Lubars in The Wall Street Journal

"This is how I see excellence, it embraces generosity, humbleness, and sincerity of effort. At it's heart it is about never being satisfied. It has nothing to do with perfection. I'm not a perfectionist. I'm an excellence-ist." - Chef Charlie Trotter in Hemispheres
