That’s a great point about other disciplines. Why should writing require some outside arbiter? Is it because these other disciplines consist in crafts that require significant training, whereas anyone who’s literate can start writing a book at any time (and therefore, the threshold for entering the medium is much lower)? I do hope you’re right about learning self-editing skills. I actually just made a YouTube video about how to self-edit: https://www.youtube.com/watch?v=3mmLEuH9x28
I've done four covers through Ebook Launch for two different series, and they've knocked it out of the park every time. In one case they were creating brand new covers based on a high-concept mashup idea. In another, they were following in the footsteps of a different designer, who'd already established the look for an existing series. Both times -- whether coming up with something totally new or sticking to an established style -- they did fantastic work. I love my Ebook Launch covers!
In fact, Pressfield writes, “Resistance is experienced as fear; the degree of fear equates to the strength of Resistance. Therefore the more fear we feel about a specific enterprise, the more certain we can be that that enterprise is important to us and to the growth of our soul. That’s why we feel so much Resistance. If it meant nothing to us, there’d be no Resistance.”
