Andrew,
In talking with you, you helped me think clearly about how to develop a profitable ebook. You also helped me understand how to market an ebook while also satisfying customers.
The idea to give free updates of your book to past buyers is brilliant, and leads to happy customers who then trust you.
I think one of the most important things you told me was that the best marketing for my ebook will come from my own content, such as a blog. A blog should demonstrate to my audience that I can help solve their problems. That way, they will be more open to paying for my solutions later on.
Another big way you helped was by telling me to set a timeline for the book, and to just get it out there.
Best, Justin
