Here’s a choice for you. You can have one of two things: Something good, or something that’s crap. Which do you choose?

Quality always matters. Always. Even if you’re an author who practices rapid release (where quantity takes priority), quality is still a thing. The definition of “quality” might change from instance to instance, but it’s pretty much universally true that given a choice, people want something good more than they want something bad.

Authors can successfully put quality first, or flip the script so that better-than-average books are able to command better-than-average prices. Right now, though, your head might still be stuck in the old world. You might be thinking that taking the time to make better books would be awesome but pointless. In that old world, you can make the greatest books in the world … but good luck finding people willing to pay more for them.

I promise you, those people exist. You just have to stop thinking like a rapid release author before you can begin to see them.
