Via @BubbleCow, here is publisher Michael Hyatt’s take on the role of an author in the publication process:
This is why I believe would-be authors would do well to focus on those aspects of the publishing process they can control. That begins with writing the best manuscript possible. If the author doesn’t do that, then the size of the media platform is irrelevant.
It comes down to this again and again. Don’t complain about the wind, the rain, the slippery surface or the homicidal car drivers if you went out with square wheels on your bike.
