Help me narrow down my options

<p>So, I'm currently a senior in high school preparing to go to college. I've already been accepted into a semi-decent(not an ivy, but not completely unknown) college in most of the areas that I want to study. The issue is that there are a lot of things I am interested in. I have "narrowed" my interests down to the following:
Finance
Economics
Mathematics
Physics
Philosophy
Law(to some degree)
I am fairly certain that I want to double, maybe even triple major, but the issue is in what. I am interested in several career options(professorship, investment banking, banking, financial analysis, research, and mathematical modeling to name a few). Ideally I intend to go straight to graduate school if at all possible. Currently I am debating between finance-economics, finance-mathematics, finance-mathematics-economics, mathematics-economics, and mathematics-economics-physics. As you can see, that is a fair amount of options. </p>

<p>Can anyone here offer advice? </p>

<p>Law is a post-graduate professional school major that does not require any specific undergraduate course work or major. So it need not be a constraint on your selection of school and major.</p>
