Recently I read a blog from Inkpot about keeping notes, and how she went through notes on stories she wrote years ago.
Although I too kept most of my notes and stories from way back (not that long ago, really!), I also have another problem which is not a good one. I tend to keep all versions of stories I write (now that I write on a pc). Therefore I have story X version 1, 2, 3.. and so on. I start a story, it's not going well so I re-start it from a different angle, yet I can't bring myself to scrap the first version.
I tend to be a hoarder anyway but I think this is pushing it!
