<p>There’s no reason you can’t pursue your passion while in undergrad. Most grad students have been involved significantly in research as an undergrad (it’s pretty much expected), and it’ll give you an opportunity to find out if what you want to do is what you really want to do. For example, I wanted to work in semiconductors more than anything. I did my entire minor in physics taking all the worst classes just to help me prepare. Then I worked in a lab that did semiconductor research. Hated it. Went to grad school to work on large, bulk materials and love it.</p>
