What career should I pursue?

I'm soon to be entering my Senior year of high school and I've yet to hammer out which career I should pursue or what I should major in once in college.

A little about myself:

I'm a 17 year old male. I work part time at Safeway and I've been promoted there. I also work onion harvest with my dad during the summer. I consider myself a very hard worker and my employers do as well. Ever since I was a toddler I've worked at the local Farmer's Market. My brother and dad have been major role models in my life, I've taken from example pretty much. I consider myself fairly educated, 3.6 GPA. I take advanced courses; AP English and Honors Math.

My personal time is usually spent with friends, jogging, video games, or on the internet learning. I like to party and have a good time. I try to play as hard as I work haha. I'm very social, I have a close inter-circle of friends followed by a broad range of associates.

I have a wide range of interest. Politics and history definitely ranks near the top. I love reading about new technology. Obviously I have a passion for agriculture since I've been raised around it. I have many other interest but I'd say those are the major ones.

The reason I ask this question is because I've been researching career options recently. As I said, I have a deep interest in politics but it doesn't sound like a very stable career path. I'm really family orientated and I'd like to live comfortably, both of which are kind of difficult to maintain with such a career (or so I've been told). I'd like to branch out and not follow in my brother's footsteps and become a farmer, although I have nothing against farming. I love technology but I can't see myself in that career.

I see myself as a leader and I see myself helping others. I'm still young but I feel I have very good ideas I would like to pitch forth to the public that could better our society. My friends hear most of these ideas because I'm very vocal with them and I feel very passionate about them. I guess this is why I see myself involved in politics and social affairs. I can't stand the current form of government, but that's another 5 paragraphs right there haha. On the political spectrum, I'd say Ron Paul has greatly influenced me.

Thank you for reading and I appreciate all the answers. I'm open to hear from anybody on this.
