I'm extremely disorganised and scatterbrained. The notes I have made for my novel are currently strewn about my bedroom floor on the backs of envelopes and chocolate wrappers. I need to go to a stationery shop and buy some books or something. How do you organise your writing? Do you have, say, a notebook for jotting down ideas as they come to you, a big pad of paper for first drafts and a CD rom on which to actually write the thing? What about notes that you have made, and now feel sure you won't use? Do you throw them away or save them for a rainy day? What colour pen do you write with? Do you think it makes a difference? Any other organisational tips?
