Pat Flynn talked about "Lessons learned from my first book launch (and behind the scenes look at my brand new book project)".
His first book was written after he'd been laid off. Let Go is about his journey from losing his job to becoming an entrepreneur. It was easy to write, because it was about his personal experience.
He has a blog and a podcast, among other things, and is currently writing the first book of a series. Each book will be based on a specific problem and very specific solutions. There will also be courses available for each book.
He spoke quite a bit about the writing process and said a couple of interesting things. He's had to control his urge to constantly edit what he's writing, because a lot of interesting things are lost when the writing sequence is interrupted. Some people even take the delete key off their keyboards!!! [How funny!! I'd never heard of this!]
