I can't say that I know of much off-hand...for me the turning point was actually failing a few classes. That seemed to finally give me the wakeup call I needed to light a fire under me, so to speak. Not that I recommend failing, per se, that's just the way things ended up for me. One thing that certainly helped me was to take a slight detour from my graduation path for a semester to take classes that genuinely interested me. I found that taking a few courses where I was more willing to put time in out of sheer interest helped hone those same habits for classes which maybe were less interesting / more tedious. Hope this helps, and best of luck!
