What would a good career path for me be?

I'm only 15, so it's natural that I would think about my future.

For a while, I had it set in my mind that I would become a priest, because it seems as though that is what makes the most sense.

On the other hand, I figured that I should probably have a back-up plan in the event that I do not become a priest. There's a girl who has an awesome personality and seems to be so pretty; she's the only girl that I have ever been very attracted to. I went out with her two different times, and I honestly keep trying to shake her out of my mind. I'm definitely not expecting to marry her or anything, but her sheer presence makes it seem to make sense for me to have a back-up plan. She is also one of my closest friends.

Right now, my classes are, for the most part, designed towards becoming a priest, even though I attend a public school.

I figure I can just put out the classes that I'm gonna take so that it would be easier to give a decent reply.

AP U.S. History

In case you can't tell, my strengths are foreign language and mathematics. If you could suggest suitable careers, that would be great.

I already posted this once, but it really didn't seem like it was in the right section or whatever.
