I worry that people think you have to go to a university to be a good writer, which is categorically untrue. I don't think I learned how to write at Oxford. I did not go to any creative writing classes or anything.
People question what I thought of Oxford. Students used to talk about the 'Oxford bubble' because the place can make you feel cut off from the rest of the world. I would forget there were places like London that were not centred round libraries and essays.
