I did books recommended from here, and lots of math stackexchange searching/questions.
I started with Basic Mathematics by Lang, Eccles book on Mathematical Reasoning, A Course of Pure Mathematics by Hardy combined with the lecture notes of MITs honors single variable calc and Polya's How To Solve It, currently doing Advanced Calculus by Loomis & Shlomo.
I would imagine if you're interested in advanced math you would go to free university seminars from visiting professors and network with whoever is there as a self learner.
I get up 3hrs before work everyday and read a chapter then do as many exercises as I can. Repeat until done, or I get stumped and skip that exercise then come back to it later.
