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?
