We all are likely familiar with the notion of mathematical maturity, you sort of get an intuition for how to put mathematical ideas into context and make sense out of them as you do/read more and more math. I've noticed that it's much easier for me to pick up a graduate level math text and grasp the material now than it was, say, a little over a year ago. Over the four years that I've been serious about studying pure math, I've noticed this trend continue and there has clearly been a great deal of accumulation. My questions are (to those who wish to answer): (a) What is your experience with this sort of thing? (b) Does ease tend to vary logarithmically with how much time you put in studying mathematics? That is, I assume it can't continue to feel easier and easier to get through dense material without dropping off as the complexity of the material goes up, but the more I do/ read math, the easier it gets to look at another area of mathematics.
