15 year old requires acting job

At the age of four i wanted to be a ballerina, at the age of 6-7 i wanted to be a gymnast, from the age of nine i have wanted to be an actress and maybe a part time singer. Today i am 13 and still want to be an actress. My friends have already told me that they would be the first people to watch one of my movies. I want to prove to my parents i can accoplish my dreams, like my younger brother who makes it to 'Nationals' for running. I have been attending 'Helen O'Grady Drama Academy' from the age of 11 and i just have begun 'Sydney Talent Company'. I have always wanted to go to Fox Studios to act, but my parents would not allow it because it is much too far away. I hope somebody out there can help me become a famous actress all over the world. After all i dream about it every night, but one day thoses dreams have to come true. I need to start one day.
