I'm a Molecular Biology major with an Asian Studies minor

. Minors aren't actually useless, it's very good and will definitely enhance your resume when looking for jobs. If you show you're multifaceted employers will eat that up and will want to hire you simply because they know you aren't a one trick pony. The thing with my minor is that not only am I encompassig so many types of classes with it (for example Japanese, East Asian Religion, etc) but I'm getting internships I need for my major because they like the dedication I show and said speaking an Asian language will be even more helpful than having a science minor with a science major.
So do whatever you like for a minor that you couldn't do with your major.
