How do I continuing to self study mathematics on my own after a B.S in math? I might go back to grad school later or I might never but I want to continue my studies how do I pick a direction of something that interests me? Is there some sort of curriculum I can follow? For reference I've taken most of the basics: 2 Semesters Analysis, 2 Semester Algebra, Topology, Combinatorics, Number Theory, Complex Analysis
