Enjoyed maths at school, was good at it. My hand was always up in maths classes, I would stay behind and try to ask questions for deeper reasoning after class etc. Compare that to constantly being held behind in other classes for turning in homework so bad the teachers were sure I was mocking them (I was tbh).

Went to university to not just study maths, but hopefully become a professional mathematician. I did as much pure maths as possible, don't like stats or applied because I don't like using my memory. Got disillusioned at uni, it is a fucking factory. No creativity, just standard memorisation. It was quite humbling to me as well reading these theorems created by 15 year olds that I found hard to comprehend. Of all the uni courses, I think I felt much more at home and strongest atgame theory. Let me tell you know that Game Theory is the most important mathematical subject there is at the moment in my opinion.

To be honest I could talk about maths for hours, I could probably talk about pi for 20 minutes before getting a headache and having to lie down. I will study it in my free time when I'm older and fingers crossed, like to contribute, however small, some progress in the mathematical field. But at uni, I couldn't wait to get a real job and contribute to society rather than deal with abstacts that probably won't find practical human use.

If you want to know what real maths is, you'll find it in this link(it's a pdf) http://www.maa.org/devlin/LockhartsLament.pdf

Read page 3 '"Mathematics and culture" to end of page 5. The article is about how maths is badly taught to children and it is all true but that's another debate.

Also for anyone with a bit more interest in maths in general, I recommend this documentary, YouTube - Dangerous Knowledge (chap 1of2) = Pt 1 of 5 - BBC , itsveryinteresting!
