Thank you, David. I like all your points. Your first one reminded me of a personal post I wrote a few years back in honor of a dear friend I had just lost (it's been 3 years now -- I can't believe it). It's called "The Difference About Differences," and if you care to read it, it's on Medium:  https://medium.com/this-happened-to-me/the-difference-about-differences-3a1c1665c9e6#.pto78dgm5.
