For notes related to books I'm writing, I've wondered whether I should organize my notes better, but I do find that the action or scrolling through them and seeing odd juxtapositions of ideas helps to stimulate my own ideas and creativity.
I was enchanted to see Phil Patton's piece in the New York Times on "Our Longing for Lists." The piece was illustrated with the image of Johnny Cash's to-do list (which, by the way, reportedly sold at auction in December 2010 for $6,250).
This spring I had an epiphany about the mixed feelings I was having about where I live. I knew that deep down there were absolutely things I loved about where I lived, I just was in a funk and needed reminding. So I made a list.
