Writing through writer's block

As I begin to make some progress with the seventh (and final) book in the Legacy of Androva series, I got to thinking about how I could improve my writing process. There are still times when I hit a mental block in terms of how to take the story forward, even though I know my characters and the worlds they inhabit very well. And next year I'll be starting something brand new, so I won't even have that familiarity to fall back on. Now seems like a good time to come up with a strategy.

I already know that I can't outline, so plotting my way out of writer's block is not an option. The stories I invent whenever I try to figure things out in advance are--how can I put this?--not the best. And sometimes, not knowing what's coming next is a good motivator for me. I keep writing because I want to know what happens.

So, after due consideration, here is my Top Ten of ways to beat the block. (As always, I feel I should make it clear these are based on my own experiences and I am not an expert!).
