Hello there! I will be studying Mathematics and Physics in University in approximately 2 months. I really enjoy Mathematics and have done some introductory Calculus. I have looked into Spivak's book "Calculus" and, although written very well, I just tent to find Calculus boring. However, when looking at books like Hardy's "A Course of Pure Mathematics" or Rudin's "Principles of Mathematical Analysis", I find these to be far more entertaining. Now, it is my understanding that Real Analysis is generally a more formal approach to Calculus (which I very much prefer). Is it possible to simply skip the "formalized" (from high school at least) Calculus in books like Spivak's and start an Analysis course in something like the books mentioned above. Is that a wise move or will I be missing important topics not found in Analysis books? Thank you.
