I recently checked out a book called "Six Word Memoirs", which is a collection of just that, life stories summed up in six words.
An example (also the subtitle of the book) is "Not quite what I was expecting."
other examples: "I like girls. Girls like boys".
and my favorite so far: "Googling my name gets zero hits."
What's your six word memoir? Take your time and make it good :-D
