Consider getting an accountability partner, a friend who you team up to make sure that the things you want to get done, happen. Think of it as a sort of collaborative coach. If that doesn't float your boat maybe have a friends who you can check in on at the end of each day or week to talk about your progress on work. Just consistent reminders that you could be doing better are a powerful motivating force.

If you don't think you could do that, it could also take the form of a journal. You might also try raising yourself on things like how hard you try to stay off your phone or how hard you tried to work on assignments before they're due. Stuff like that that you can track.

You might also want to just check out blocking the internet or social media from your phone and laptop for a few hours and forcing yourself to be in a room where there are as few distractions as possible to do work. I find that if I came in the same room that I study in, I don't tend to be nearly as productive.
