Sometimes, when you’re looking at the same information for the hundredth time and it’s not clicking, you just need a different perspective on the situation. I’ve heard from friends that when they’re writing and get stumped, it helps them to stand up, do a lap of the house, and let their fingers rest while their minds puzzle through the writer’s block. I myself have learned that if I sit upside-down on a couch or chair, that helps me literally get a different angle on what I’m doing. Something about it -- blood flow, spinal comfort, maybe laughing at myself -- helps me shake things out of stasis and get back on track.
