A few weeks ago, I reached out to winners of the 2016 TAA Textbook Awards and asked them to answer some questions about their textbook writing. I had so many great responses I decided to create a three-part series to share them. The first installment focused on why they decided to write their textbook, how they got started, and what they do to boost their confidence as a writer. The second installment focused on how they fit writing time into their schedule, what software they use, what their favorite pedagogical elements are, and what involvement they have had in marketing their book. This last installment in the three-part series focuses on the advice they have to share with other authors and what they wish they had known before they started their writing journey.
