Sometimes it takes the better part of a lifetime to find out what your passion is, but in my observation, if you do, it might be the best part of your life.

I've come to recognize what I call my 'inside interests.' Telling stories. And helping people tell their stories is a sort of interpersonal gardening. My work at NBC News was to report the news, but in hindsight, I often tried to look for some insight to share that might spark a moment of recognition in a viewer.

'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.

My tides were fluctuating, too - back and forth, back and forth - sometimes so fast they seemed to be spinning. They call this 'rapid cycling.' It's a marvel that a person can appear to be standing still when the mood tides are sloshing back and forth, sometimes sweeping in both directions at once. They call that a 'mixed state.'

You cannot look at a sleeping cat and feel tense.
