Choosing a major is the single most important opportunity you have to shape your own undergraduate education.  The Academy's core curriculum is both demanding and rigid; there is not a lot of room for academic experimentation.  For this reason, the stakes are high.   Your major determines what your schedule will look like (and feel like) for the next three years. It is important to remember that committing to a major is a decision about your education, not your career.  Any major at the Naval Academy can choose any service selection.   English majors become pilots, nukes, SEALs, NFOs, surface warfare officers, and Marines.  English majors who leave the Navy after five years go to med school, business school, and law school.  They become diplomats and bankers, writers and stockbrokers, teachers and entrepreneurs.  You do not need to have the rest of your life figured out in order to pick a major; you do need to have an idea about what kinds of courses you want to be taking in the foreseeable future.

No matter how you end up making your living, you are going to be putting together documents that you want people to take seriously--business plans, legal opinions, book proposals, scientific articles, memos on how to save the world.  English will give you three years of intensive practice at these tasks.   You'll have conversations that force you to articulate positions, you'll have useful criticism of your prose, you'll learn to write and think.  You'll become confident and savvy.

A final note:  although it's a good idea to talk to lots of people during the majors selection process, remember that you are the one who has to buy the books, do the homework, deal with the teachers and take the exams.   Don't let anyone pressure you into majoring in what they majored in, or what they wish they had majored in, or what they think it is a fine idea for any bright young upstanding American to major in.  This is not about them.  This is about you.

Go for it!
