Thanks for asking Emile: That was the strangest part. One Sunday afternoon (around dinner time), I heard the Buffet story in a video talk from Fr. Mike Schmitz. Thought it was interesting. The very next morning, I was reading a book at the gym (one that was released about a month ago), and there was the exact same technique in my book (without any reference to Buffet but literally the same top 25 and 5 lists). I thought, "OK, I guess someone is telling me I need to do this..."
