To me, fearless is not the absence of fear. It's not being completely unafraid. To me, fearless is having fears. Fearless is having doubts. Lots of them. To me, fearless is living in spite of those things, every single day.
I'm not a perfectionist, but I like to feel that things are done well. More important than that, I feel an endless need to learn, to improve, to evolve.
