I don't know what to do with my life?

I'm a sophmore in college. I'm majoring in political science. I figured I'm gonna get that no matter what but I don't know what I want to do anymore. I was originally gonna go to law school and just be a lawyer. But I've been taking a step back and really thinking about it. I do martial arts, and I'd like to do something with that. Not opening a dojo, but maybe becoming a cop and helping people. Another road is just applying for the FBI. The problem is neither one makes as much as a lawyer would, its just I would rather have an exciting job, rather then just a desk job. I don't know. I feel like I'm at a crossroad. I don't know what to do. I don't expect you guys to make the decision for me. But knowing my situation, I just wanna hear some feedback on what you guys think would be good for me?
