I heard about a Man on Dan's podcast who wanted to combine his passion of theology with teaching and I was playing along trying to come up with ideas. I thought he might use his passion to teach people about certain life skills. I consider the Bible to have some good psychology information. There are also people who are so narrow minded that they will not even listen to advice from someone they consider secular. I thought he probable has one or more good books he could write using his passions. I just thought I would pass that small idea on.
One model I think would be very useful in this case is Kary Oberbrunner's "18 Streams of Income" approach to book publishing. Basically, you write and publish a book and build an entire brand of associated courses, seminars and workshops. I've included a link to the ebook as an attachment. It can work for both fiction and non-fiction.
