My final quarter of school is a little over halfway through, and I'm finding it very difficult to stay motivated. I've been accepted to and am planning to attend a good graduate program next year, and, while I need to make sure I pass all of my classes, I don't have any reason to put much effort into them. I'm falling behind in my classes, and while I don't think I'm in any danger of failing, having a backlog of work increases my stress a lot. Every time I sit down to get anything done, I just think about all the other things I could be doing, and I totally lose my patience and focus. I've been pushing myself for ~4 years now and I'm just losing the energy to do it. Any advice?
