Book about writing books as new business cards

From an author friend

Charles Jo

Dear friends,

My newest book is at Amazon today. It’s already #4 at Amazon for its category.

After writing so many books, I wrote a book on how to write books. By writing books, you can get opportunities for more projects, jobs, and so on. See http://blog.andreas.com/2014/08/18/why-you-should-write-a-book/
