Your 40s are a major trough. About the age of 50, feelings of satisfaction begin to rebound and keep rising into your 50s, 60s and 70s, with health being a major factor.

In the beginning when I sat next to Tom Brokaw on the 'Today' show, the stories I was interested in were those having to do with women and children and learning and health. In those days, 25 to 30 years ago, that was called soft news, and not in a nice way.

I think my children know that Mother's priority is to be with them first. But I don't think it has to be an either/or situation. Work is very important to me, and it wouldn't be in the best interest of my children for me to stay home seven days a week.

Most of us in the baby-boom generation were raised by full-time mothers. Even as recently as 14 years ago, 6 out of 10 mothers with babies were staying at home. Today that is totally reversed. Does that mean we love our children less than our mothers loved us? No, but it certainly causes a lot of guilt trips.

'Good Morning America' exploited Joan Lunden's pregnancy, but you won't see me bringing my babies on the air. The only reason I'm talking about the babies at all is that they've been with me on the show since I became pregnant. After a while, I had to acknowledge this pumpkin tummy.

I think the success of a talk show depends on how true it is to the personality of the person hosting it. The shows I really admire, like 'Oprah' and 'Ellen,' are distinctively like their hosts, so I think my show will be successful only if we try to stay consistent to my own sense of myself.
