The expression goes "Ignorance is bliss," which I guess is true in one sense: not knowing that there's something out there you don't know. The people of Earth, moments before their planet is destroyed in the introduction of A Hitchhiker's Guide to the Galaxy, are blissfully ignorant. They don't know about the aliens that are moments away from demolishing their planet, and they don't know that they don't know about it. They have no idea there's even information out there which might make them concerned.
Amazon provides sales and author rankings, so you as an author can keep tabs on how your book is performing relative to every other book on Amazon. That is literally every single other book that can be purchased on Amazon.com. That is a lot of books. Before my book launched, I didn't know this existed. I didn't know what I didn't know.
I was a happier man.
The problem with Amazon's sales rankings, from my perspective, is that they are too spastic to be of any real-world use. One day, I'll be soaring pretty dang high. The next day? Brick wall, shipwreck, death and destruction. The next day? Hey, good again.
It's basically an easy way to put myself in a bad mood for no substantial reason. Or a great mood, for equally no reason.
We'll see how long it lasts, but I'm taking a break from checking those numbers. Here's hoping it makes me feel better.
The problem, of course, is that I know there's something out there I don't know, which is about as far from bliss as you can get.
