Hello , I have something called Asperger's Syndrome and I would like to find a narrow topic or highly specialized field to study in the future as an Aspiring pure mathematician. But I have little or no experience in Mathematics , that's why I'm asking this question. I obsess about geometrical pictures that could be imagined by even a layman. It would also be nice if you provided an example simply of what the field does in simple terms and how you experience it's beauty when encountering it. Or you could even provide a favorite picture of the mathematics involved and how it actually looks like!
