I used to love math until my senior year when I had to take my introductory to advanced math and real analysis courses. Before that I had taken up to elementary linear algebra, and I loved and excelled in all of my math classes so this was my first introduction to proof-based math. I liked math because it was like a puzzle I had to solve.
I liked math enough that I was considering doing my master’s in mathematics, but if it is only going to get harder and go more into proofs I do not think I would survive. It got to the point where I had to switch my major to statistics and finished my math degree online.
