Where do you write?

Practical Blogging talks about the coffee shop as an ideal place to write, based on an article in USA Today.

This is a familiar idea. In fact, it’s been something of an obsession for me since I ran an article in Estates Gazette on the idea of coffee shops becoming the new offices for mobile workers nearly three years ago. But lately, my thinking has been turning on its head. Why are these places more conducive to writing than more conventional work environments? I certainly find it easier to do any form of writing in a coffee shop, or on a train, or on a sofa, than I do in my work or home office.

What’s the psychology of that, and how could we use it to improve our work environments?
