Speaking as an academic editor (also trained in creative writing), this piece offers really excellent advice for people who aren’t familiar with the writing process or don’t know where to begin. Lots of people get so overwhelmed by the megalithic IDEA of a large work that they don’t realize it actually becomes very simple (and much more painless) when you break it into really small steps. This is especially simpler, as you say, when you’re writing about facts rather than composing something more subjective and artistic.
I hope more people see this piece because I’m sure it can help many. Great work!
