My dreams will they ever come true?

I'm a 14yr old girl and my dream is to become an actress my mother went to an arts school and got offered a directing job. My father is a different story, my family is very artsy and ever since i was little i was put to sing and dance. I put on shows for my family with my sis. Lately this dream is very strong and first it was just a phase when i was in my first drama show. Im really passionate about it to be honest. I know that there are hundreds of people dying to be an actress. but honestly i love it i dnt want fame it wud b better if they could allow more privacy. Im ok at singing and dancing. my personality is very corky and i was thinking about this summer i would start an acting class. i joined the school play and did not make it, but then again no freshman or sophomores made it. so idk. I really like it but if I'm average i feel i do not have a chance. Idk this is probably stupid. I should probably forget about it. i love making movies at school, and i love it. idk if someone could recommend anything thanks in advanced!
