kaizen, man.

One of the ideas that has stuck with me from my masters program is the hijacked-once-Japanese-practice of Kaizen, or continual improvement.  Changes need not be big to make a difference, but they must occur over time.
I just link-surfed from the The Thinking Chick to Presentation Zen to a post on kaizen in PowerPoint design that kept my old favorite word come back to me.  The gears are turning, turning, turning!
