Actions vs. Repeated Actions

I read this quote today from Aristotle, and I thought I'd share it:

We are what we repeatedly do. Excellence then, is not an act, but a habit.

I like how he turns excellence from a singular act into the plurality of habit. Anyone can be nice, kind, generous, creative, inspiring, loving, or giving once, but excellence comes only in repeating that action...making it habit...making it permanent to you.

I found that an interesting thought.
