passion is scary

i watched this talk today about artists and how there is a certain amount of anxiety that necessarily accompanies their work. there is a constant worry that it won't be good enough, that no one will like it, that it'll never live up to expectations, etc. and all i could think was that that's not something unique to creative professions. i think it is true of anyone that is following their calling in life. being a teacher scares the shit out of me. what if i can't be a really great teacher? what if i can't make a difference for my kids? what if i can't teach them things? what if i never live up to my expectations for myself? that worry, that anxiety, comes from doing something you are truly passionate about. if your work doesn't scare you a little bit, it isn't what you are meant to do.
