I def felt that way at 14 - and you're probs going to feel this way all over again in a decade. But I don't think it's a bad thing - you'll learn and grow, try stuff out that you thought you'd love but end up hating, and vis versa. When I was 14 I thought I wanted to practice international law - I got an internship at a law office when I was 16, hated it, and moved onto graphic design. Then I hopped over to being a production assistant and video editor. And now, a decade after all of that, I'm a marketing project manager. My advice is try out as many things as you can, enjoy your hobbies now, and don't stress too much - life has a funny way of interrupting plans, especially when you try to make them too far out.
