On New Year's Eve, journalist and former Parade Editor-in-Chief Janice Kaplan made a promise to herself to be grateful during the coming year and look on the bright side of whatever happens.

As we find out in this episode, it made a big difference to her life. Janice discovered that how she feels has less to do with events than with her own attitude and perspective on life.

Her recent book "The Gratitude Diaries" began after a survey she had done found that 94% of Americans thought people who are grateful live richer lives. But less than half those surveyed say they practiced gratitude on any regular basis.
