It's really important to know your audience when you start writing something. For example, if you want to write a dystopian novel, usually teens and young adults read such books, so you want to modify your novel and theme a bit to better suit their interest and understanding. You need to decide on which group of readers you want to write for so that you can adjust themes, motifs, characters, etc.
