I'm in my last year at uni, how can I motivate myself?

I didn't have this in college, but in highschool. It is something we called "senioritis." It is really hard because you have a lot of other things that you would rather be doing. However, since it is your last semester, you should probably be taking mostly major classes in subjects you are really interested in. Try to think of it as the last time you are going to be taking these courses that you really like. Also, you will probably miss school once you've been out for a little while, so all I can say is enjoy it while you can.
