With a few marketing bets, I've now passed $70,000 in revenue in three and a half months. Releasing the book series early has proved to be a great move, as I get to write it at a healthy cadence and folks get gradual content drops too.
Some early, consistent feedback has been that readers prefer this, so they aren't overwhelmed with a 20,000 word book to absorb all at once.
My goal is to get $100,000 in revenue by year's end.
