I'm 15 and idiotic. I want to either be: Professor/Researcher for Chemistry or Biology, Software Engineer, Electrical Engineer, or a Doctor.
Forget software, it's never-ending education for a slim chance to be noticed among the literal hundreds of thousands of other candidates, only to lose your job one day to some punk fresh out of college who's skills make yours look obsolete. Professor is a 50/50 profession. Most who try for the education path aim for the college/university level, and only end up teaching highschool. It's one of those careers where you either get the top job and life is great, or you struggle in lower positions your whole life, stuck at the career because of the time invested, but dissatisfied because your dream was only cheaply chrome plated and made-in-china. Researcher, same thing as professor, but with a tenth the number of available jobs, but a more lucrative living for those who DO hit the top. Chem vs Bio, hard to say what's better. It really depends on what you are best at, both lead to a wide range of possible paths.
Now of the rest, Electrical Engineer is a great choice. If you enjoy it, that's a plus, because it's one of those careers that can never be eliminated by new technology or a change in economic situations. The world will always need engineers, the better you are at it, the more you make. Only downside is unions, they're a boon or a curse depending on the union itself and your personal work ethic. And doctors, you can't go too wrong. Even a crappy medi-center doc (at least, in Canada) makes better cash than most other professions. There is tough competition in the schooling, lots of very bright Asian and middle-eastern students to go up against, but there are other options if you can't hack it (pharmacist, vet, dentist, and nurse are all common alternative paths).
Just some friendly, if jaded, advice. Don't make the one big mistake, don't go with a broad skillset. With the boomers retiring, there is more job security for someone who can do a job, and do it insanely well, than there is for someone decently good at a couple different things.
