After reading the whole interview I have a few more concerns though, I don't like how Meredith Finch says that she's not planning that far ahead.
This is a personal preference but I simply love long-term planning. Almost everytime that an author tries to create a plot without a proper build-up it always end-up in disappointment halfway, it's cool if they want to do short and fun arcs but it's better if their story follow a certain theme and direction.
