When I first decided to become a math major, all I had taken was single-variable calc and linear algebra. I had NO idea it was going to be as hard as it was. I thought I was pretty good at math, my calculus professor encouraged me to declare a major in the field, and I wanted job security (I was also an English major). I also decided to do this all in my senior year. When I started my analysis and abstract algebra classes, I realized how little I actually knew about mathematics. I wasn't a superstar student anymore; we were all fighting bravely for what we hoped would be a grade higher than a C+. Some struggled more than others. I was somewhere in the middle. The classes were so hard, and required so much out of class work, I didn't think I was going to make it through the year. In one year I took Multivariable calc, two semesters of analysis, two semesters of algebra, numerical analysis, financial math, number theory and ordinary differential equations. It humbled me to the point of self doubt. I scraped some As, A-s, B+s, a B- and my FIRST ever C. In this one year (june to august), I realized that I will really be a student and a learner of mathematics forever. There's so much out there, I can't possibly ever learn it all, or even come close to understanding it all!
