Who you would like to read your book vs ideal reader
Most of us know the type of people we would like to read our books. However, I find this to be different than your ideal reader. It's so easy to envision a group of people who enjoy a certain genre or trope, but it's another level to be able to outline your ideal reader. That ONE person with specific likes, dislikes, hobbies, quirks, etc. Knowing who that person is makes it so much easier to feel like you are talking directly to them.
