Fiction writers often encounter the dictum to “write what you know.” But what does this really mean? How do you do it without re-hashing your own life story? If you’re in the Boston area, you’re invited to Grub Street, Inc., for a seminar on April 6. We’ll talk together about the limits and liabilities of the principle as well as some more rewarding (if sometimes risky) ways to employ it. The workshop will include short exercises plus excerpts from John Gardner, Mario Vargas Llosa, and others. Bring your thoughts and questions about work-in-progress and possible new projects.
