I was going to copy this quote:

"We all live with the objective of being happy; our lives are all different and yet the same." ~Anne Frank

(http://www.brainyquote.com/quotes/authors/a/anne_frank.html)

Then I found this one, too:

"Life is rather like a tin of sardines - we're all of us looking for the key."
~Alan Bennett
