Stuck mid-writing? Whatever you do, don’t just sit there staring at the blinking cursor. Get up and walk around. You don’t have to down tools entirely, especially if you’re pushed for time; just going to use the bathroom or making a cup of tea can help your brain switch into problem solving mode.
Change your scene, breathe differently, move, look at stuff – even if you end up looking through it. Give your brain a chance to unstick itself. Some of my best ever EUREKA moments have come from being stuck and making a cuppa. Keep thinking about your writing, though – don’t get distracted or you’ll end up doing the housework or watching TV. What a total waste of time when you could be working on the next big thing, right?
