Personally, I think once you reach a certain point during the journey of being an author, you start developing this internal scala between constantly battling one's inner demons creeping up, thinking no one's ever gonna read your works because you feel like they're mediocre, until you turn your frustration into a determination to be able to fight God himself because you can literally bring your imaginations to life and it's not like anyone's gonna stop you from writing something so insane that might even rival the greatest classics.
Like, it all comes down to getting in the right mood and just get to it.
It's some cycle to love and hate tbh, but it also has some magic to it. It keeps me motivated, even when there's a chapter with little to no feedback xP
