Struggling to shape that sequence? Straining to sum up that scene? Stirring to... uh... symmetrical? Well, s-words aside, it sounds like you need to jump into a car with your best mate! No, not the back seat to take part in suspect activity, the front two!
A year or two ago Mutt and I drove down to a dock a couple of hours from our respective places to see this awesome missionary ship before it got decommissioned. Having nothing else to do but let the car do all the work, we started talking about our ideas... as we always do. What followed was perhaps nothing short of the best brainstorming session we'd ever had.
See, it turns out that a long car trip is like crack for your creativity. You have a sense of purpose in trying to get somewhere, but that doesn't require much concentration. So you're free to brainstorm free of distractions, or just to sit there and mull over things quietly with no pressure to talk. Andrew Stanton and Bob Peterson of Pixar fame would do this when they were stuck on Finding Nemo, driving all the way down to L.A. instead of flying.
So if you've got a creative mate and you're stuck for inspiration, pick an ice cream parlour a good few hours away and start driving. Just... be sure you can afford the fuel.
