I've kept diaries since 1979 and have a trunk-load of books filled with everything from teenage angst to cartoon strips to travel writing. I've previously read my teenage diaries out at Oh Dear Diary events and last year created short stories from specific journeys for those I travelled with.
My big project now is to mine them, in both traditional and experimental ways, from coding algorithms to handmade photomontage to short travel narratives. That should keep it interesting and help me get to grips with what I've actually got.
No links yet as I think I'm going to make it anonymous for now.
