I had to quit maths at high school because it was just too frustrating memorizing apparently useless and meaningless formulas and definitions. My teacher wouldn't explain (she probably didn't even understand) what any of it was. Later, at the university, the beauty of calculus suddenly made sense of everything, and I got a renewed interest in maths. I now hold a master's degree in algorithms and take university math in my spare time for fun. I curse my high school math teacher's name to this day. I hope she retired early.
