In her latest book, Make your Mess Your Memoir, writer Anna David tells her compelling story of addiction and coming out on the other side. She also gives excellent advice on turning your own personal difficulties into great copy. I've known Anna for a while but it wasn't until this interview that I really learned her fascinating story. Anna talks about how she dated Matt Damon, her addiction to cocaine, the time Tom Berenger threw a book at her head, and the secret to writing a book people want to read.
