1. When I’m writing a book I only read other books that somehow inform my book. If it doesn’t serve my process — no matter how much I want to read it — I don’t. I suspect there are a lot of people who will give the opposite opinion (take a break from reading about your subject matter, etc.), but I’m not one of them. This is your time to be completely and justifiably obsessed. So go ahead — bask in the madness.
2. Non-fiction shouldn’t mean poorly written. Writing is writing and art always counts. Make your book beautiful to read and you’re more likely to communicate your messages to your reader.
3. Don’t focus on the promotional aspects of social media. Just share your passion for the subject matter as it filters through your writing process. The promotion aspect will be an organic extension of your passion.
