Exact same goal here. I can nail 11 over and over, but 10 is going to take some careful choices and more than a bit of luck for me. It means you only get 2 non-answer guesses.
I'm almost there. Some mornings I don't feel like doing it, but don't want to lose my streak. That's the first sign that this is less fun and more of a chore. I give myself less than a week.
