My father really, really pushed me to excel in a way that I resented for years and then realized had really worked for me.

I was doing the family grocery shopping accompanied by two children, an event I hope to see included in the Olympics in the near future.

So you're getting squeezed at both sides. You're taking care of your mom and dad and you're still doing caregiving with your kids, which is not easy. But I think overall, there's a level of satisfaction that might be unparalleled.

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'll tell you the truth - I went to a women's college, Barnard, the most selective college for women in America today. If there's one thing I came out of Barnard with, because it was a women's college and a great institution of higher education, it was fearlessness.

The closest thing to an outline is, because my memory is so bad now, if something occurs to me that I think might be important or pivotal, a lot of times I'll scribble notes down somewhere until I can get back to the book. Of course half the time I look at those notes the next morning and think, "What was that about?"

When you leave college, there are thousands of people out there with the same degree you have; when you get a job, there will be thousands of people doing what you want to do for a living. But you are the only person alive who has sole custody of your life.
