Susan, you asked me a great question on twitter that I cannot answer in 140 characters, so I'll respond here instead. You asked what my major discovery or insight was between writing 1st and 2nd versions. I'd say that my biggest awareness is how easy it is to lose track of the vision, after we have created it and done all the work to set thing in motion. Circumstances change and we get distracted. Life happens. And then one day we look around and realize how far we have drifted off course without even realizing it.  This is true at a personal level as well as for teams and organizations. It's not enough to just create a vision. We have to put strategies in place to support our ongoing awareness and focus. For this edition we added a new chapter on "Staying the Course."  Thanks for asking the question, Susan.
