The things an early retiree has learned since he retired. Your list or mine may be slightly defferent, but these provide a good reminder (and lesseons for younger people) of what is really important.
I particularly like the quote he references from Hunter S. Thompson:  “Life should not be a journey to the grave with the intention of arriving safely in a pretty and well-preserved body, but rather to skid in broadside in a cloud of smoke, thoroughly used up, totally worn out, and loudly proclaiming “Wow! What a Ride!â€
