Computer Security, Certified Ethical Hacker: Good career choice and if so best way to get there?

I am going to be a junior in high school this year and I need to start deciding on things like colleges and careers so I can plan courses and my future to be able to attain an end goal. I want to do something like Ethical (White hat) hacking but I haven’t the slightest understanding of how to go about planning for college things. Should I take more online courses or should I go to a fancy IT focused college or a simply a community college? I don’t know what degrees are good and I can’t find anything good on breaking down the college process for someone who can’t even drive (teenagers in general, the driving statement was simply highlighting my point as opposed to that being the only reason why its confusing). So 1) Is it a realistic choice 2) How do I go about it 3) Simple explanation of college, careers, and jobs?
