Curing writers block with martial arts

Recently I got stuck on my next novel (a story about kung fu and artificial Intelligence). First I blamed how busy I got at work and adjusting our lives to the East Coast. But truly it was because I got so into my survival journey as a white belt in Brazilian Jiu Jitsu that, despite my thirty years training striking arts, writing about non-grappling ways of fighting just wasn’t happening. Not surprisingly, like so many things in the process of writing this book, the answer was hiding in the challenge. On not resisting the threat, but using its own energy against it. Suddenly, it all clicked. I made one of the characters be a BJJ fighter who helps the main character develop her ground game, just like I am doing with my own skills. And voila! Writing is furious again.
