I want to learn calculus by myself, I searched a lot on internet as well as math stack exchange for suggestions for best calculus books, I know a lot of famous books like Stewart Thomas but I do not like the way it is presented. I want to learn rigorous mathematics from books like Apostol Spivak Courhant Serge-Lang, but I am not sure if I can take them, the level of proofs and logic they need, I am afraid if I buy them and not able to solve because high advanced level they are, some motivations is needed and also guide me if I need some more books as prerequisite to understand Apostol Spivak Courhant
I am reading books like how to solve it by George Polya, if you can suggest some books which refine logic and thinking please suggest me.
I am also someone who enjoys mathematics but not want to learn just basics. its more like dream if I one day able to read and understand books like real analysis by Walter Rudin
THANK YOU
