Jobs for intelligent people...?

I am in 9th grade, take the hardest cles offered at my public school (ranked 200 nationally out of all public schools in the USA) and have a 4.0 and come from a wealthy family of doctors. It wasn't until recently that i questioned not wanting to be a doctor, because i recently realized im pretty sure i dont want to be one. Are there any other proffessions that make good money and that you have to be pretty smart for? Me and my older sister are both expecting to get into pretty good colleges. We both do extracurriculars and sports, and she now has a 4.6 and a 2350 on her SAT, and we are both about the same intellect. I don't want to go to a good college and pay loads of money, just to end up doing an easy, low-paying profession. Im good at math and science, i hate history, but i love english and reading. What professions do you think would work for me and, if possible, please give websites that explain the professions. Thank You!!!!
