I have many areas of interest, how can I study all of them?

Any well-ranked college or university should have depth in all of those subjects. I recommend that you take classes in all of these disciplines in your freshman year and see what you like best. Different disciplines have different approaches to the material (quantitative vs. qualitative, specific research methods, ways of framing questions). As you take coursework, you will probably gravitate towards a particular discipline or two. If you genuinely like them all, pick a major and take courses widely in the rest. You shouldn’t feel compelled to double or triple major or complete double minors if that’s not where your interests take you.
