How to Get into Category Theory?

Question

I've always been interested in "Pure Maths" and Category Theory, because I'd like to understand the mathematics/logic behind programming more deeply and rigorously (also, just the concept itself is cool).However, I don't have a very advanced mathematical background (The highest that I've learned is Calculus 2), so I don't know what the "pathway" towards Category Theory is-What are the prerequisites and/or some resources to learn Category Theory?

Learn to read and do math proofs. Then learn some abstract algebra and general topology so that you can understand examples you'll meet in category theory. Then, bam, you're ready for category theory.
The other way is to dive straight into category theory. Doable, but difficult. You'll be learning how to parse math arguments and argumentation style specific to category theory and examples from other branches of math along with the theory(from those branches AND category theory itself). Tough shyt if you ask me.
To get started with learning how mathematicians present and defend their arguments, there's free and really good Book of Proof by Richard Hammack[0].

I was in the same boat a year ago and went to a mathematics professor teacher and he suggested this book:
Conceptual Mathematics by Lawvere[1]
The book teaches category theory to, smart, highschool students.
It's a great start.
After that I went with:
Category Theory for Programmers by Bartosz Milewski [2]
Next I would go with anything by David Spivak.
Now I understand that: A monad is not scary, it's just a monoid in the category of endofuctors" ;)
