I'm not saying that students should disregard the financial impact of selecting a major. Of course not. College is expensive, and everyone should take the time to do the math as it relates to their choices. But college isn't just about the monetary return on investment. And to reduce an education to such a blunt calculation is to ignore the multitude of rewards that have both nothing and everything to do with long-term success. Specifically, the opportunity to learn how to interact with people from all over the world, the ability to question what you know, the chance to push your limits, and to explore the unknown with the relative safety net of knowing that the worst-case scenario for failure is probably little more than a bad grade on a paper.
