No. It's just purely a matter of practice. If you don't understand it now, you will with enough time and repetition. I had classes lectured by Maurer some time ago. At first it was all gibberish but with time and repetition and practice everything becomes clear. It's interesting because I would say Maurer really puts effort into being _extremely exact and precise_ and even reading this I can appreciate that now. There's an element of that which makes it much easier and clearer to grasp than a math paper which is skipping over some basics and definitions and is more inexact because it leaves you guessing at times.
