I lost interest in math after calculus, when it stopped being about results and more about abstract and complicated squiggles on the page . Elliptic functions are interesting because it seems calculus-like (such as elliptic integrals and the theta series) but this weird set/category theory stuff just doesn't do it for me.
"Stopped being about results"? I think you're referring to the building-up of the vocabulary required to attain results. As an analogy, you learnt to count (1,2,3,4,…), but then when addition and multiplication were introduced, it "stopped being about numbers, and more about abstract and complicated operations on numbers". Yes, fine, but addition and multiplication open the gateway to the study of the primes, from which most of the results of number theory follow.
