I find that taking a walk along a wooded area, stream, or within a quiet park often inspires me with a story. My mind begins to wonder about the past life of a character I've been stewing over or even about the struggles my hero/heroine may be facing.
It's amazing how stepping out for just a thirty minute walk or meditation in the sunlight can invigorate my creativity. I'm not quite sure if it's the sun's rays or just the fresh air that awakens my subconscious. Whatever it is, I believe it's definitely a simple; however, an effective way to rejuvenate a stalled story line or produce a new project.
Even watching squirrels as they play can get my mind spinning about a fight scene between the hero and villain. The mating dance of birds also provide some stimulating love scene ideas for a story. Yes, it's quite the show observing these detailed; yet, simple displays of nature within its own environment.
So, does nature inspire your stories or stimulates your creative side? Is there something else which gets your subconscious mind to take over with story ideas or plots? I'd love to hear what's worked for you.
