I've been texting with someone who's working on her first novel, and she asked me for five words. So I sent them, and two days later she sent me a quite imaginative story inspired by those five words. When she sent me five words back, I at first balked - being in the middle of a rather enormous novel - but later that day I realized I had brought my most recent conflict to an unanticipated resolution and my novel desperately needed the kind of "left turn" that enlivens any good plot line. So I took those five words on a lengthy beach-walk and mentally composed a fascinating little story that became a dream in the novel, that supplied the spark for a wholly unexpected new conflict - just the left turn I had been looking for.
You never know where the next inspiration is going to come from. And I'd certainly recommend the five-word drill as a good way to keep the faculties loose.
