Today I began sorting through them, yes, no, maybe. Some of them were journals from various courses and since graduating. In one of them I came across a page with an idea from years ago that I'd underlined and highlighted and mentally bookmarked to keep. I put it aside but later it somehow got torn up and thrown in the rubbish. Luckily I remembered it in time and spent an hour sifting through torn-up papers until eventually finding it. The fragments are now taped to a piece of card and I scanned it to make sure it doesn't get lost again.
It's a strange idea but I've never seen it anywhere else so it's worth keeping in mind. It's to do with art and time. When things settle down I'll start thinking about how I could make work based on it.
