This journal isn’t mine, but it could be. I use sketchbooks that are huge to just capture ideas. (I also always have a small one with me.) They end up having drawings, lists, mind-maps, pockets pasted in and other paper inside, and pages and pages of writing. I save them all. I’ve needed two lines for a poems before, and have gone back into my journal and found the perfect lines written two years past. I think there is a kind of magic in a journal, don’t you?
