The world has lost a real hero, and we are all so deep in grief. But Michael's loss is felt so deeply because his life was lived so fully.
To me, he was a friend, mentor and inspiration. I was always in awe of his work ethic. When he wrote, he was all in, focusing for hours and hours without distraction. And yet, he often ended his emails with something like "back to work ... unless you need me." And that was even more of an inspiration. His heart was enormous.
I think I'll miss him every day. My deepest condolences to his family and loved ones. We were all so lucky to have known him.
