I take a shower. Showers are the key to unlocking the squirrely plot points of my novels. I have had my best ideas in the shower and right before falling asleep. Showers are a better place to get ideas because I can get out and write them down. Before sleep is precarious because I don't always have the energy to write it down. I always think, "I'll remember this amazing idea in the morning!" and then never do. Lol. Now I pick up my phone and put those ideas in Evernote. It's safer.
