No need to spend a lot on courses or fancy books. Just get the Harper-Collins "Dictionary of Mathematics" for about 10 bucks or so, virtually the entire corpus of mathematics laid out in very readable and digestible articles. It's equivalent a Master's Degree in Math, IMHO. If you're really interested in math, this should get you going.
Also, find a guru who can mentor and answer questions.
