“Everyone who tells me they don’t have time to write, I just say, ‘One scene a night for three months, and you’ll have a movie—you can even use the weekends.’ It’s possible to be a writer if you want to be a writer, even without all the time in the world….After doing the dishes, instead of turning on the television or reading a book or going to the movies, write one scene. Whatever you do write one scene.”
Oscar-winning screenwriter Bruce Joel Rubin (Ghost)
