I was a craft teacher at a local college. My income needed a boost. I was reading a magazine one day and thought: this reads like one of my teaching handouts. I write handouts all day. I can do this. So I wrote to five craft magazines. Four ignored me. One said come in. I bluffed it. Said yes before I knew if I could deliver. She gave me a monthly column and told me one thing I'd done wrong with each submission. I fixed it. Did it again. Nineteen nonfiction books later, I still use the same approach. Start before you're ready. Fix as you go. What's something you started before you felt ready?
