As any responsible adult will tell you, try to go to school before pursuing your dreams (whether it's to be an actress, or a circus clown) as, in case your dreams fall through, you have a degree to fall back on. You can even major in theater and gain valuable skills, as well as valuable connections that could help you later on in a career in theater arts.
Also, school and college will teach you how to form sentences which are persuasive, intelligent, and grammatically and mechanically correct. Not that I'm saying that you need to learn that skill.
