On this Thanksgiving Day 2017 I am grateful that I am able to sit down quietly and read Isaacson's biography of a man who died almost exactly 500 years ago. A man whose story describes the turning point in history , the Renaissance, when the unknown craftsman became the artist of the posterity, a common man could be come a celebrity, whose personality would itself become subject of admiration and study for the ages. As Walter Isaacson noted about Einstein, the lives of such personalities are now more relevant than ever - they lived life on their own terms, depending not on community or tradition for their achievements, their own inventions their own creations their only reward. And so it is for every man, woman alive today - we have Google, Amazon, and (yuck) Facebook - and can get all the information we want, buy anything we need to satisfy our dreams and follow where our curiousity and imagination will lead us ; 'Stay hungry, stay foolish' as Steve Jobs would say. We are no longer bound by custom and tradition, but as Steve Jobs again reminded young Stanford grads 'You are all going to die soon' Death is greatest change agent of life ' and we must define ourselves in the time we have by what we do, what we create, what we leave behind. There is no instruction book, unfortunately, on how to be unique, how to be creative, how to find and keep your identity in a world where everyone can be a prophet on the Internet, everyone a genius, everyone a madman. We can only give thanks that we have such marvelous examples provided to us - by one of the greatest biographers (along with David McCullough) of all time. Happy Thanksgiving!
