I think the Buffett example maybe wasn't the best illustration of compounding because it sort of comes off like, "see how much money you can have while you're on your deathbed!" WGAF.
And I think the really old, sick person angle applies even before you're really old and sick. Like, I used to dream of traveling the entire world and doing all kinds of crap. But the older I get, the more I'm like, "meh, whatever." I expect this trend to continue and by the time I'm retirement age I'll be fully content watching the birds in my back yard, which is incredibly inexpensive.
