I've played so many jobs where I'm fearless, but it's far from me. I wish I were like that in real life.
Most importantly, I agree that the truth of these matters should be determined by interpretation of scientific evidence - experiments, fossil studies and the like.
There are always going to be times when it doesn't flow as much as you were hoping. So of course I'm going to fail. And when I do fail I hope I fail better and better, again and again. I am happy to fail.
