Gina from Maestro Consulting Group posted the above saying in response to my post today over at HBR on "The Delicate Art of Being Perfectly Assertive."  I think it is a lovely and wise saying.  Indeed, it is a perfect companion to the "the attitude of wisdom," the ability to have the courage to act on what you know in concert with the ability to doubt what you know and do.  Gina, great stuff!
