Q: Don’t try to write a book everyone will like.

There is no book that everyone likes. Think of your very favourite book. There are many people, many of whom you probably like and respect, who do not like that book. Just write the book you want to write. If you try to please everyone you’ll play it safe, compromise and end up writing something bland that runs the risk of no one liking it. Believe in your idea and accept that it won’t be for everyone.
