I can't say anything specific yet, but I'm in the middle of my favorite assignment of the year: profiling 3 of the 15 winners/fellows of the AARP Purpose Prize. These go to people over age 50 (generally considerable older) who have started an innovative organization or business that fills a social need. Over the years I've profiled a dentist who works & educates in underserved neighborhoods in the Twin Cities, a woman who helps wounded veterans in ways that the VA can't, someone who trains women to be sound engineers, a man devoted to elevating his home city of Baton Rouge, and many more. All of them have been fascinating, relentless, & humble. What they have in common, I would say, is a willingness to stick it out no matter how long it takes or the odds against achieving their dream.
