When to Write

This last week I've been traveling across the United States taking the legendary road trip. I had promised myself I'd get started on the next book in the Keep of Time series. I deliberately set up a travel schedule that left me time each day to write. I had all the materials ready, my most inspirational writing books at hand, and.....
That's right, I didn't write.
Every writer I've ever talked to has had this problem in some form. We plan the perfect writing getaway and it doesn't work.
The answer? That, I think, is something each writer had to arrive at on their own. The only thing that works for me, is to write. No matter what, write. About anything. Anywhere. Anytime. But damn well write.
