thats the problem i had (and still have), i think nearly everyone that is young doesn't really know what they want. Even though I don't know what i want to do, I know if I go in the direction of something I enjoy, like taking a course which really interests me i know I'll end up somewhere close to what i enjoy. THough I don't know what, I know that whatever it is could achieve a happy life. But I think the best thing to do, is just start a course doing something that you like doing. Because it is so much easier to study and learn when you are doing something you enjoy. And you'll know that your career path ahead of you is going to be around a subject or field you really enjoy.
