I find it difficult to get rid of things I wrote or drew as a kid.

Same here (I love seeing drawings I did when I was a little one). But it goes to silly degrees - in that I've still got all my high school books. Which is kind of ridiculous when you think about it. Hmm. I might have to bung all those in the recycling next time I see them (won't get rid of what I've got of my junior school books though).
