New York is a city where it's particularly hard to be poor, not only because everything costs twice as much as it does elsewhere but because over-the-top affluence is part of its identity.

One of the things that got me on this topic for this book was that when I was researching the column I wrote in 2009 saying that I was stepping down from my column at "Newsweek" because I wanted to make room for newer, fresh voices out there, I discovered that in the year I was born, 1952, the average life expectancy of an American was 68. I was shocked by that figure and every time I mention it I hear a gasp from somebody in the crowd. Now, of course, we're more or less at 80, so that means that we've gotten 12 additional years.

I know a lot and have written a lot and have thought a lot about motherhood.

The truth about your own life is not always easy to accept, and sometimes hasn't even occurred to you.

Adolescence is a tough time for parent and child alike. It is a time between: between childhood and maturity, between parental protection and personal responsibility, between life stage- managed by grown-ups and life privately held.

Well, I'd like to think I am, and I'd also like to think that we're all having a lot more fun getting older than we pretend. It was interesting to me when I first started working on this book that I'd mentioned that I was writing a memoir about aging and everybody would moan and groan and carry on.

Ideas are like pizza dough, made to be tossed around.
