This is a week of change.  My two daughters are back in school, the older one now in middle school.  My wife and I are back to teaching for the Fall 2014 semester, and I have a new course in “Physics of Community”.  The MOOC on “Creativity, Innovation, and Change” that I am co-teaching — with more than 58,000 students enrolled — is ending.  It’s a time for both nostalgia for a great Summer, and hope for a great Fall.  It’s a time to set new a new WIG (Wildly Important Goal).  Not 10 WIGs, not 5 WIGs, and probably not even 2 WIGs.  1 WIG.  What is yours?
