I sometimes wonder what people do who don't have the desire to write. Do they watch a lot of television? Exercise more? Hit the clubs? Spend more time with family and friends?
My days revolve around my family, friends, occupation, and ice skating (aka rehabbing my ACL). But whenever I get a free moment, my mind immediately flits to the characters in my book. I'm imagining the next scene, contemplating a character's motive, thinking about red herrings, or brainstorming ways to improve my plot.
What do non-writer-people think of during their free time? What fills their minds when they're not thinking about their families, jobs, religion, hobbies, etc...? Do they think of anything else? Do us writers have a special compartment in our brain for the imaginary that other people don't?
Writers are a breed unto themselves and often only writers can relate to how another writer's mind works.
