Interesting topic, thanks for sharing! I think the first impression about a certain topic that needs to be well understood can play an interesting challenge in the learning process. I remember myself hating music theory when i was in school because of the way the teacher was introducing it to the class, then when i had curiosity and a real desire to understand it i could clear my mind from negative thoughts that had been fixed in my mind before and i became more able to understand it .
Sometimes taking a break from learning something can be helpful to continue learning with a powerful fresh attitude.
