The single most frequent question I get as a writer is not where I get my ideas or how does an author find a publisher - though those two questions are certainly high on the list.

But the most popular question is: what do I do, what kind of physical or mental activity do I recommend, to encourage or facilitate writing?

The preamble and proviso for my answer to this question is: Not all writers are the same.  Different writers like and rely upon a different things.

But here's my secret: walking.

A mile or two or three, around the long block near my house (3-4 times around the block is a mile).  I find there's nothing like it when I need to think through a story or a scene, decide where a character should go or be when I'm feeling stumped.

I like driving, too.  I guess there's something about motion that gets my creative energies flowing.

But I like walking even better - mainly because it not only gets my mind and imagination going, but makes me feel physically good, too.

So there you go.  Next time you're stuck in a story - take a hike!
