The deadlines are much, much longer with books. When I was a reporter, a lot of times I'd come in at 8:30 a.m., get an assignment right away, interview somebody, turn the story in by 9:30, and have the finished story in the paper that landed on my desk by noon.
But at the same time you can't assume that making a difference 20 years ago is going to allow you to sort of live on the laurels of those victories for the rest of your life.
