Library lovin'.

Study, study, study.
There is no shame in studying. Especially in college. I have often been referred to as a "closet nerd" for the fact that in high school no one knew the serious extent to which I approached my academics. Come out, come out, wherever you are. Because if you do not come out of the nerd closet and STUDY (consistenly and correctly) that you will not do well. Period.

The Goldie Locks complex.
Find a spot. Somewhere comfortable enough to be content yet formal enough for an academic setting. Close enough that you want to go yet far enough away that you won't want to leave after only 20 minutes of your study session. Somewhere secluded enough to stay focused yet populated enough that it isn't depressing. Comparable to Goldie Locks and her porridge ... you have to find what is just right for you, the rest is easy.

When you love the library a little bit too much...
Balance is key. Studying should usually be priority number one, but in my opinion, when it consumes your entire college career you officially have a problem. Learning can occur outside of a classroom, out of textbooks, and outside of the library, believe it or not. Some of the best lessons I've learned at college have had nothing to do with any of those three. On the other hand, some have. Do not spend so much time with the library that it could have the potential to be your significant other you know it THAT well.
