A professor in undergrad gave me the tip to get excited or even feign interest when reading dense written material in order to retain more.
After trying it throughout a difficult class I was amazed at how well it worked. I applied it to every other academic thing I didn’t want to do and noticed immediately how much easier and enjoyable school was. I still use the “fake excitement” trick for my work all the time.
Also, it’s kind of like a Trojan excitement because after I fake the intense interest I do genuinely become interested more often than not.
