Motivation.....Help me people!?

I'm stuck in on a nice day doing so much uni work and revision for exams. I've been here for 4 hours now and losing the will to live! Can you give me any good advice, cool quotes or uplifting music i can put on youtube in the background? At the moment i've got on 'real wild one' (pretty woman) so i can screech along and make myself feel like i have actually got a life besides uni hahaha! I know i can do it.....just need some other people to tell me i can! xxx
