That's the "right" answer.
But there's another answer. There are tricks, but they're personal and you have to find them for you.
When I have a cold, as I do now, I love to take AlkaSeltzer orange cold medicine. I really don't like taking medicine in general, but I love taking this stuff! I love plopping the tablets into the water and watching them fizz. And it works! It really works! And I know why.
Because I love the hissing, spitting little bubbles!
Surely all of that hardworking carbonation does something!
If someone offered me a pill that did the same thing, even a bit better, I'd still choose the bubbly, gritty tasting drink. The fizz means it's healthsome and efficacious!
I know this is the placebo effect. I know it. But that's the lovely thing about the placebo effect. It works even when you know you're using a placebo.
A friend of mine with a Ph.D. in chemistry said that she likes to uses 3 drops of some sort of tincture when she can't sleep. "I put it under my tongue for three times the placebo effect," she told me.
My writing trick is similar. When I'm having a hard time putting my butt in the chair or opening the Word documents instead of checking Facebook, I take time to regroup and get "energized" to write.
I might light a candle or hold one of my favorite rocks and close my eyes and direct my concentration toward my work. I imagine myself taking energy from the object or ritual, and then settling in to do my work. And it works.
It's not magic, but it is a kind of trickery. And it's no less useful for the fact that I know it's all in my head. I love my rocks. I love the candles too. I love the moment where I "take" and focus my energy with them.
I know I could mindfully focus myself on my writing without these things, but it's the "trick"--the "magic"--that I want. It's the fizz of the thing.
And that's my writing trick.
Do you have any writing tricks that help you get the words on the page?
