I am thinking that the OP might be a high school student based on his/her name...hoping to graduate from college in 2017?
Even if you are in college, just get exposure to both fields by volunteering/shadowing in both. You can volunteer for legal aid, and you can volunteer at a local hospital. I also suggest doing at least one day of shadowing in completely the opposite environment (i.e. rather than altruistic, giving, public-service like legal aid and volunteer hospital service, go shadow a high-paid lawyer and/or a highly regarded research physician if possible) so you see the entire spectrum.
I think dr's tend to be kind of disparaging of lawyers, but each path has its own finely tuned suffering...I certainly couldn't spend as many hours doing the kind of work my recently graduated lawyer friends do...I'd fall asleep. They think of med school and residency like their own personal hell. It should become clear, which, if either, is appropriate for you.
And there are sooo many other paths out there. I think the title of your thread indicates that you don't really know what those are yet.
