im in a very strange situation. i have recently started self-learning real analysis, using rudin and pugh simulatenously, and i am enjoying it a lot. the problems are difficult but i find i can answer most of them (well more than half anyway) yet, when trying to re-learn calculus via spivak and apostol, i am stuck at the problem sets. they are extremely difficult and i find i cannot solve most of them (solve ~30%?). the proofs i also find more convoluted in these elementary texts. now... is it okay to continue the way that i am? and does it make sense to continue with analysis even though i dont get those calc books? i was told analysis is way harder. and while it is, the problems are more straight forawrd.
