Tom Petty was right

You take it on faith, you take it to the heart

The part about being a writer that isn't talked about very much is that craving to be rewarded with feedback from readers. You want a tiny bit of validation that you've crafted something that people connect with.

But not only is publishing the ultimate long game, getting a review or other contact from a reader is very hard to come by. I'm not sure what the correlation is of buyers to reviewers but I think it has to be quite striking. That is, I think only a very small percentage of buyers actually post a review. 

So, until another one comes in, Tom Petty was right . . .

The waiting is the hardest part!
