You know what needs to be done when you're a writer. You know what the job is, particularly if you're an African American writer, or if you deal with people, or if your subjects are poor people or people who need voice. So you don't really need to know whether or not you are doing the right thing. What you have to be wary of if you're doing the right thing to the right level that will surpass your own life. I'm hoping that my work will surpass my own life.
