While I'm not going to give you a speech here, I will say that you probably groaned (perhaps audibly) when you were told that you had to use three resources from the library. You, like every student before you (myself included), are currently confident that you don't need help finding quality sources because you don't know how bad you actually are at research. When you are unskilled at something, it takes experts to point it out because you don't know enough to know what you don't know. In this case, librarians are the experts at research! The video explains this phenomenon known as the Dunning-Kruger Effect, and there are links to library resources supporting why it matters to you as a student!
