be a famous fashion designer

i so want to do this but i dont really know how to get into the industry. its quite intimidating, i know there are courses available at tafe and uni and stuf but they have such limited spaces that i doubt i would get in. i know i should just give it ago i mean if 20 people get into the course each year why cant one of them be me? but still im plagued with insecurity. but this is somethng i really wanna do i mean i devote pretty much my whole life to fashion and at the moment im more worried about not having a formal dress than i am about my year 12 exams. i shouldnt let it get to me but people have always made me feel that im not good enough for this industry, like i dont seem committed to art so therefore i obviously dont want it just as much as the next person! its so annoying because it would be a dream come true to see people wearing my designs and i think i want it more than anyone else…why am i the only one who believes i can?

this dress is only one of my many designs
