I mean you kind of already write a book yeah?
Yes. But it was too abstract hehe ;)
A good author knows what people want to hear. You, on the other hand, only know what you want to hear.
That explains why JK Rowling is constantly changing the background information of her characters to suit her audience.
Like dumbledore suddenly being gay and things like that. Still trying to tell people what they want to hear and make them like the book more
