David Bowie has been my #1 since I started keeping track at 10 years old. He's had more impact on me than any other public figure alive in my lifetime. I remember thinking last Friday on his birthday how grateful I was that he was still out there producing art, but it hit me that at 69, I should start mentally preparing myself to see an old David Bowie. That it was time to especially cherish anything and everything he gives us from here on out. Two days later he was gone. 
It blew my mind to hear his voice crack singing "tremble like a flower" in "Let's Dance" and I was never the same. It was provocative for a 10 year old to hear a grown up break a rule like that. And nothing is more influential or tantalizing to a 10 year old than seeing rules get broken. I've probably spent more time thinking about David Bowie in my life than anyone other than God. Both are puzzles we may never solve in this life. Maybe in the next.
