My friend Scott Ginsberg has another great post on building your own creative environment.  The best tip:

Make a list of five alternate environments for your creative success.Perhaps your art is more conducive to the park, the bus station orsitting in a public square. If so, great! Experiment by displacing yourself regularly.

Onceyou’ve narrowed your list down to a few options, visit them regularly.Learn to incorporate various components of creative stimulation intoyour “portable creative environment.”

That way you can thrive anywhere!

As someone who has been on the road a lot lately, I'm going to give it a try.
