When I was running my writers group in Los Angeles, one of my favorite warm-ups was haiku-writing. One particularly memorable haiku session revolved around honkus, inspired by Aaron Naparstek's book, Honku: The Zen Antidote to Road Rage and his website honku.org. (Listen to a fun interview with Naparstek from NPR). As you might imagine, in the freeway centric Land of Dreams, we had plenty of first-hand experience to draw on.
Haiku's something I use when I'm stuck, too. Sometimes I just put down whatever piece of content I'm developing and stretch my writing muscles a little by composing some verse. It's like yoga -- releasing tension and spurring creativity. Most of my haikus are crap, but they provide a welcomed reset from the regular work, and relax me when I'm feeling frustrated about a piece that isn't going the way I'd like.
