To improve my study habits, I'm trying two pretty straight forward strategies:

1) Noticing when I'm wasting time on the internet and not having fun, but rather just trying to waste time, and immediately switching to something productive. 2) When doing an assignment that doesn't involve using a computer, going to the library with whatever I'm doing and leaving my computer behind (the library is 2-3 minutes away from my dorm).

I've only just started using 1, and I've only used 2 once, but both sound like they should work and seem like they have so far. With 1, I often end up switching from bored internet browsing to reading one of my open tabs, which is more enjoyable and almost sort of productive, so even that is an improvement I think. When I used 2, I was surprisingly productive and surpassed my expectations. For unrelated reasons I had to return to my dorm, and various distractions made the time in the library about 3x more productive than the time away from it.
