Explain to me the secrets of Calculus

I will not take a Calculus class, but I know it contains a multitude of mind opening secrets, creating a sort of enlightenment wherein your perspective of the world and everything you know changes, but like a psychedelic drug, you can never describe it unless you make someone else go through it.  I refuse to go through the experience, but try to explain to me, a mere mortal, what these mind opening secrets and changed perceptions are.

Wrong. You start to get at some topology and whatnot, but it doesn't do anything for anything. All you do is learn more about quantifiers and how to use them, which is important for the definition of limits. But other than that, there is nothing.
