"I'm not convinced that there's any such thing as "writer's block." I suspect that what we like to call "writer's block" is actually a failure of nerve or a failure of imagination, or both.
If you're willing to take chances, risk ridicule, and push the envelope, and if you've managed to hold on to your imagination (the single most important quality a writer can possess, even slightly more important than an itchy curiosity and a sense of humor), then you can dissolve any so-called block simply by imagining extraordinary, heretofore unthinkable solutions, and/or by playing around uninhibitedly with language. You can imagine a wordplay your way out of any impasse. That's assuming, of course, that you're talented in the first place."
Tom Robbins, asked by New Times: "What Do You Think Writer's Block Is and Have You Ever Had It?"
