Many writers and creative types have little habits they engage in when they need to think. Some shoot hoops, others go for a walk and so on. I shuffle cards. I keep five decks of cards at my desk for this sole purpose. Whenever I’m thinking through an article or a tricky passage, or I simply need to come up with something to write about, I’ll shuffle my cards.
I used to keep a yo-yo around for the very reason but stopped the habit a long time ago for some reason. Think it is time to pick it back up.
