Math is hard for the same reasons that anything is hard. It is literally a mental strain on your brain.
I agree with the author in that a teacher's enthusiasm and perspective, and 'rigidity' in school can compound difficulties.
But as a physicist, the most difficult part of learning math, for me, is overcoming my own mental barriers. I need patience and focus to comprehend even the most simple sentences. If I don't want to learn/strain in the moment, then I won't.
