You know what feels really good? When you meet someone you knew like twenty years ago who took a totally different path, and then you reconnect in some meaningful way.
This has happened recently on several fronts. For instance, I just spoke yesterday to my first boss, who hired me for an internship in 1986. (I know, not every six-year old is hired for a post-college internship but there you go.)
Another example is when I reconnected with my friend, Pauline Chen, first at a dinner several years ago in Palo Alto, and most recently this past fall when we both coincidentally published our books. Hers just came out in paperback: Final Exam: A Surgeon's Reflections on Mortality. It's earned rave review, deservedly so.
