"Be the person you want to find."

I saw that as a bumper-sticker, and then when I googled it I found out it was a book. Kinda along the lines of "if you build it they will come" but it also brings up the idea that sometimes we're looking for someone who as aspects we wish WE had; and it'd be better if we aquired those characteristics ourselves rather than trying to aquire a person who has them.
