The title says it all.
Originally, it was just writing a book that people were willing to pay to read. Even one person would make me go, "Wow, someone wants to pay money to read my book!"
Now it's more like, writing a book that a LOT of people want to pay to read. After doing this for a while, I've gotten enough success that I know what "success" looks like, and anything less is a bummer.
Like a lot of indies, I used to cringe at the idea of giving away my books for free. I even hated to do the odd free days at Amazon to promote a launch.
Now, I've giving the first books in my series away for free.
I've gone from "I bleed for my art and I will never sacrifice it!" to "Kill your babies if you have to."
I still try to sneak the odd "art" in there, but it's harder now. But hey, it sure as hell beats digging ditches!
