I laughed seeing this cartoon on Debbie Ridpath’s blog: I was wearing my noise-cancelling headphones at the time (over earplugs). You have to block out the world in order to allow the imaginary world to bloom.
The subject of the blog —Podcasts for Writers — is well worth checking out. A number of good ones are mentioned, including my personal favourite, Writers on Writing (shown as Pen on Fire). Writing is isolated work; it’s wonderfully comforting to listen to other writers talking about the craft.
