Hey St. Benedict Amadeus,
So I sell a number of things. I have successfully sold my ebook that dives WAAAAY deeper into generating traffic (how I generated over 2.5 million views of my content and how I leveraged that into an email list — though currently that is down seeing as I'm revising it due to tweaking and improving some strategies), I work with another successful blogger and sell his course work through an affiliate agreement, I am building my own course work, and I sell physical and digital products through other affiliates.
There really are so many things you can sell.
What types of things are you thinking about selling? What are the biggest things you've been working on? What is your mission and the goals you have with your writing/blogging/content generation?
(P.S. I hope this answer helps — let me know if you need further explanation)
