Gemba Panta Rei is one of my favourite blogs about Continuous Improvement and Lean. Here is a great recent post that is worth a read:  A Life of Mistakes by Cynical, Unreasonable People

It includes three nice quotes from George Bernard Shaw that you might want to use in discussions about continuous improvement and Lean

• A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing.
• The power of accurate observation is commonly called cynicism by those who have not got it.
• The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man.
