Financial talk

I still havent figured out what I want to do with my life yet, and I'm already signing up for classes for my junior year of college, where I need to start taking classes for my major, but I dunno what to take. I want to do something to help people, and to make a pretty big difference in the world that people can actually see in progress and that many people will be grateful for. I also want to speak many languages and write a book or two, as well as make a lot of money. Any suggestions on what I can do exactly in order to do this, or what to major in? Oh yea, dont tell me im too young, because I'm not and I need to pick a major so I can graduate in 2 years. Then I plan on travelling the world.
