The problem isn't starting material, but feedback. How do you know that you've solved it correctly? How do you know once you've gotten it wrong and found the solution that you actually understand what is going on?

It's cool. I had to go through it for understanding some abstract algebra concepts. It was fun but didn't have time to go on.

You don't have to. Everything in category theory is fucking trivial. Just follow all the definitions and you will see there is only 1 (one) obviously way to do shit.

By studying the shit out of it and getting your hands dirty. Just like every other subject.

Learning category theory is literally pointless unless you know many different algebraic or topological structures. It is a useful tool to keep your mind in order and makes some things easier to remember. However there are very little new and meaningful results in it. It makes for a terrible thing to study for its own purpose.

this. category theory for the sake of category theory is literal fetishism. you know that feel when something in math just clicks for you and it's awesome?. category theory is chasing the dragon of this feeling, it's literally just giving different names to the same thing over and over again to make yourself feel good. fucking shame.
>t. my university is filled with category theory fetishists including undergraduates
