Like millions of others, I have a “collector gene” (my wife Yukari would call it a disease). I get excited about checking things off lists and, especially, completing a list. I’ve visited 107 countries, all seven continents, and all 50 states; I own every book Seth Godin has written; and I’ve been to 111 Grateful Dead concerts. I saved all the credential badges from the hundreds of events I’ve delivered talks at over more than twenty years.
