Here is the closest I come to a diary... my sketchbooks. I have kept them since 1975. The only reason I remember is the image I did of my Dad, with the date clearly on the newspaper.
I go through two or three per year, dating them on the cover and spine when finished. They become a priceless image and idea mine. Likewise, this blog has filled a Diary roll over the last two years. I don't get too personal, but I do journal my ideas here.
now I seem to draw on anything... then scan them into the computer.
Copping out? Maybe. I need to pack for school...
