As with all problems, ask first "What is my goal?" Then be realistic.

If you want to make money, choose a solid major in a needed program. Then add a foreign language.

If you want to develop an appreciation of the world in which we live, choose something like foreign policy, history, and add a foreign language.

If I had it to do it now I'd choose a major which gave me a familiarity with Africa and learn Swahili. That's a remarkable trade language which is used in a number of countries. North Africa is going to be a hot zone followed by East and West.

Whatever you do, if you don't have a goal you will likely flounder, be unhappy, and not do well at anything.

And if you think you will become a billionaire, astronaut or President, give it up. Those are driven people with incredible discipline and a lot of luck. People talk about Newt Gingrich being lazy. He may be, and he has a Ph. D. in Economics, has been the Speaker of the House and is smart as hell. I should be so lazy.

Anyway, that's my advice. Have a goal, something toward which even the most boring day can be considered a step toward it, and then move.
