Have you heard of the Six-word memoirs? Can you tell your story in six words? Many people tell it well.
See them at http://www.smithmag.net/.
Some of my faves:
"It all changed in an instant"
"Sadly, we have registered at Goodwill"
"Should have crossed legs, not fingers"
"Different grass. Same shade of green"
"The caterpillar became a beautiful butterfly"
