Just note that the mentioned book, colloquially known as Papa Rudin, is definitely not an introduction to analysis, which is usually said to be "Principles of Mathematical Analysis", i.e. Baby Rudin. Even then, Baby Rudin is terrible as an introduction in my opinion, though it is quite good as a reference.

Everyone has their own taste, even with math textbooks; there are plenty of acclaimed textbooks I hate (looking at you CRLS).
> I've been ever-so-slowly self teaching higher maths.
I happen to be in a Discord server for people self-studying math. It's a pretty cool place; if you are interested you can contact u/CheapViolin on Reddit.
