For all the younger people in todays society.
Try looking into your hobbies and interests. Many people start out their careers with their hobbies and interests and find a way to get paid for it. Most times students start college with one major and completely change it by the time they're a Sophomore or Junior. What happens is, when your in high school you really aren't exposed to the vast job opportunities in the world and are typically restricted to well known careers such as a fireman, teacher, cop, astronaut, etc. Don't worry, by the time you are in college you will have been exposed to enough out in the world to have a good idea of what you want to do. You can always start out in college with an undecided major or liberal arts major to get a feel for different classes.
