It depends on what happens in the query process. Some people will get back actual notes that people are you know if you've sent out 50 queries and you don't get any response something's wrong with your query letter. There is definitely a moment where it's like okay this book is not going to work. So try something else. I have a friend that did that eight times. Eight times she sent books out on submission and it was number eight that landed her the deal. She just wasn't quite there but she would send it out and send it out. That perseverance is what you need because this can be a very demoralizing industry right.
