My ‘to do’ lists are organic things, spread across multiple post-it notes, both digital and physical (despite the attachment to my iPad mini, I’m still very analogue in some ways). They have a habit of growing dramatically during the day and usually becoming sprawling trains of thought and yellow paper. It’s a messy way to live and work, but it’s a good sign when my desk is littered with colonies of post-it notes, stacks of readings and highlighters, messes of books and loose associations of documents; a clear indication of productivity. It’s a very bad sign when my desk is clean and tidy.
