Jenny Diski writing for the London Review of Books blog on writer’s block, panic and productivity:
(W)riting is not just about writing, it’s also (and maybe mainly) about the space in between the writing, when nothing seems to be happening, or random stuff is having an incoherent party inside your head. Almost always, you do eventually start to write, and it seems that you’ve been considering after all. It’s not as comfy as writing a thousand words in half an hour, but it seems to work OK, so long as you think of it as part of a process of writing rather than writer’s block.
