Thinking about my future..?

So I've always had this massive habit of knowing what I want, when I want like right there and then. And its happened again but its stuck with me this time, and i cannot get it out of my head!! I haven't even left high school, yet im planning my way to work, in a city thousands of miles away from home.
The Plan is simple: GCSEs are Good, Good College, Half way through college go to NYC, carry out studies there in a really cute apartment with an amazing view with a modern but industrial vibe to it, the window overlooks the streets and its up high but not too high to the point it hurts my legs going up and down the stairs, I work either in the fashion industry as a magazine editor and fight to the top and chief of vogue magazine editing, or peruse a career in acting and play stars in Broadway or on television. I become rich and famous and by that time my siblings would have families, and my parents would live out their dream to Italy. I would buy a little house near by my parents in Italy so its easy to see them when I can but I'd also, three times a year buy a holiday for my whole family to meet up and just relax.
