There is a lot of pressure to think about marketing and selling, and at the same time be a creative and innovative writer.
When I look for self-published books, I mostly look for professionals in their fields who can impart some of their knowledge. That way, I know, I'm buying something of value.
As a first-time author myself, I also expect that it will take a portfolio of a good number of books before real sells start to roll in.
Interesting read, and thanks for sharing your insights.
