You have managed to overcome your fears, that's the important thing. There are things that sometimes we don't dare to do, because of fear, fear of doing it wrong, fear of being made fun of, etc. There are so many factors that influence us, that the important thing is to find the strength to overcome those fears, to dare to do what we want, to try. We may not reach the goal, but we make the attempt.
