Have you ever reached the end of a story -- a book, a movie, or a TV show -- and immediately felt a bittersweet nostalgia? You were so wrapped up in the story that when it released you, an urge to drop back into its warmth is almost overwhelming.

It's not just happy stories that provoke this feeling. All it requires is a good story: one that touches something deeply human like love, loss, growth, or discovery.

There's a lot of uncertainty in life. But this much I know: at the end of each cycle of living -- a day, a week, a month, a year, a life -- I want to have lived a story I wouldn't want to leave.
