As a teacher, a bigger problem that I have is not that people don't understand it, but that people don't care when they don't understand it. Many students seem to be just attending to a class because of peer pressure or something. They can just glide it when it doesn't click. If you feel sad when you don't understand something, I'd say you're already very motivated. Very rarely, a teacher can press a student's button to make them actually interested in the subject (or anything related to the subject), but I feel this mostly happens only randomly.
