Me in school: Math? When do I need know those details? I can look them up and just code it.

Me in high school: Computer science is way too math-y. I want to code!

Me coding php: Just make it work.

Me coding typescript: Just make it work.

Me coding scala: Just make it ... what ... how do I make it work!?!

Me asking stackoverflow: How do I do X in scala some functional programming stuff in mind in order to keep immutability.

Somebody way smarter than I: "In scalaz, a function A => A is called an endomorphism and is a Monoid whose associative binary operation is function composition and whose identity is the identity function"

Me now: Fuck my old arrogant self.
