"There’s an old adage that to write a good novel, you should write a complete draft, put it in a drawer, then forget about it and start work on what will become the real book. Nonfiction is similar. Writing takes a huge amount of practice, which means it’s a good idea to first build up a portfolio of articles, stories, and blog posts."
