I am not stating that writing more great stories might not lead to more money, but rather that "great" is relative, and it's not sustainable to write all day every day. You're welcome to try, but it's a safe bet that once you start writing daily, half of them will be less than great. It's nowhere near as clear-cut as double the articles => double the money. Just suggesting you might want to be realistic and not burn yourself out in the process, cause it would be a shame.
