When our kids were toddlers, and doing all that toddlers do so well, Paulette and I often joked that human beings start out with IQs of over 1000 but lose a point every time they fall down and hit their heads ... until they end up in the "normal" range. I recently was reminded of this when the instructional chess book How to Become a Class A Player came to mind. As (Class A player) Alan Beadle told me at a tournament in 1991, "The best way is to start out as a Master and go down!"
etc., etc. But a self-help book that takes that honest an approach probably wouldn't sell many copies.
More seriously, maybe the best way to appreciate what we have is to lose most of it --- as, eventually, we all do in this mortal world ...
