Future careers to pursue?

I'm a 17 year old about to enter my senior year in high school. I have a 4.0 and I'm and definitely going to college, but that's where my dilemma comes into play. I am very money motivated and my main goal in life is to be rich beyond belief. I've heard from adults that it's not about the money it's about doing what you love, well making a whole lot of money is what I love and what I strive to do. I just don't know what career will take me to that level. I've talked to my doctor about becoming a surgeon/doctor anything medically wise, and he told me that medical school is no longer worth it because of the debt and potential jobs available. As well as, I have spoken with an ex lawyer and she said the exact same thing. So I was just wondering if there are any careers that are on the rise or anything that would set me up for a bright future? I've got a whole a lot of time to think about it, I just believe that it is better to know sooner so I could be more prepared when the time comes.
