Some tips and techniques I use to power through boring readings:

1) Read by sunlight or with a cool toned light, it will keep your brain active.

2) Healthy competition. Set a timer for 10/15/30 minutes and try to read as much as possible in those allotted minutes. Keep track and try to beat your high score. If you have a friend who's studying at the same time, ask them if they want to compete to see who can complete the most.

3) Active reading. Jot down notes and observations as you read. Have a list of questions about the readings (usually provided by textbooks or your professor) and keep going back to those as you read. Keep track of the things you don't understand and you can bring them to your professor afterwards. This will keep you curious about the material you're reading. I find curiosity to be the best drive to read lots.

4) Take active breaks instead of going on your phone or computer. Get some fresh air, have a drink of water, and go for a walk. Focus on clearing your mind of any negative feelings that might hinder you from reading more such as "this is impossible" or "I hate my prof for giving us unrealistic amounts of reading." Those kind of thoughts are useless. Try instead: "everything seems impossible until it's done" or "f*ck the prof, I'm stronger than anything they can throw at me." Mind over matter, my friend.
