Why not try new things, such as listening to a new genre of music, enroll in a course you actually ARE interested on, not just cause is part of your curriculum, make that time (and money) count in something that you like.
First, why not re-decorate your office space, having a great atmosphere can be the answer to your prayers, when you feel comfortable and at home those hours can go by really fast.
Second, make goals, daily goals, weekly goals, whatever you decide to do, knowing that at the end of the day or the week you reached those goals will feel you up with the most self-satisfaction that not only your mind will feel great but your heart will too.
I hope you have great beginning of the week and a great back to school wherever you may be.
