I would say this even if I didn't hang out with Bloomberg folks.

People who think that they can have it all (a wonderful, engaging job; full participation in family life; time for themselves) are too optimistic.  It's totally possible to have all of these things, but not all of them 100% of the time.  Priorities have to shift; things have to give.  So I wasn't surprised by this story (here) in the New York Times.
