Whether you succeed or not is irrelevant, there is no such thing. Making your unknown known is the important thing--and keeping the unknown always beyond you.
There is one thing that you have to know, that is a deal breaker on all of it. You have to know human behavior, you cannot pass go, you cannot move forward, you are dead stopped right here, right now, if you do not know human behavior and the quality of your writing is absolutely capped at your understanding of human behavior. You will never write above what you know about people.
