My students are often asking me, 'What do you think are the most important qualities for a writer?' And one thing I always tells them is that it's helpful to be willing to sit in a space of uncertainty. There are entire years, especially with novels, where you really don't know where the project is going.
I once took a workshop with Jim Shepard, and he has this term, 'rate-of-revelation,' that has come to mean a lot to me: 'the pace at which we're learning crucial emotional information about the stories' central figures.' An ever-increasing rate-of-revelation is good; a stagnant r-of-r is not.
It was very lucky for me as a writer that I studied the physical sciences rather than English. I wrote for my own amusement. There was no kindly English professor to tell me for my own good how awful my writing really was. And there was no professor with the power to order me what to read, either.
Actually, to be an effective person politically in this country, I think you have to be thirty or over, and also you have to be rich, well-placed, you have to be close to power. And I don't think that young people, because they look young, can do much, as I think they are counterproductive.
