Of course, it is possible to Teach Yourself Advanced anything. The problem is our society has turned education to be the means to an end, instead of a continuation of an unending journey.
If you ask me most degrees expire within a year or two, once people get that Masters or PhD, find a cushy job that's it. Either they become specialists in one thing or they focus on promotions and more pay, not learning.
I am not a mathematician, but I do enjoy maths as you know maths is basically the glue that holds all other disciplines together within the different taxonomies, as well math is the path that uncovers the relationships (or differences) of the many areas of studies or of arts and sciences, okay, and mathematics. Therefore the vastness of the subject can be mind boggling, however the depth within a containable area is also of the quantum level, therefore you could happily drown in mathematics for the rest of your life. You do not need anyone to teach you because at some point there is no one who can teach you, perhps discuss some concept. For example for the past 30 years, I only met one young many about 2o years ago who happened to sit next to me in a flight from Houston to Chicago. As was customary thoe days between a white and a black guy we shared deep silence. Until he noticed my pharmacist type notebook that I was scribbling in with cryptic formulae, to my surprise he was able to relate to what I was doing, I was trying find a solution that satisfies x3=b3+c3!
and he said whay are you even doing that when half the PhD's in the world would get 2+2X2=X wrong! He was quite smart, he later told me his occupation. He was a Mathematic PhD. research scholar at the university of Chicago.
I woul late test his 2=2X2 =x theory with a bunch of Chicago High School Teachers that joined my Computer Literacy Class I taught for the Chicago City Wide College, granted not all of them were PhD's, but they were all college graduates more than 1/2 the class got the problem wrong, and tried to justfy their wrong answers in extremely unmathematical ways.
So yes, you can teach yourself, and you will be pleasantly surprised at what you discover. For example, I can categorically say that Earth will perish, I do not even know if perish is the right word, but perhaps will die one day, but contrary to popular belief it is not going to be in 2012. Let's just say mathematically we will know the end of the plannet thousands if not millions of years before it happens, why? the universe is the king of normal distribution. Planet Earth is not within the Q range of its life-cycle. And sorry Al Gore mathematics show that global warming has very little to do with what humans are doing. Maybe pollution yes, but global warming? Maths says we are simply not that significantly important to modulate.
So live your life, Earth is here for a while, not I am not saying humanity - because a few events might wipe us out including our own self destruction, but Earth will be here quite healthy for that matter. So pick up a book on princepia mathmatica.
There many Interesting topics from many university. Bu my favorite one since zi moved from Chicago to Jersey (Dumb Move). is a mixture of pure and applied maths readings from:

Good luck I also have a suspicion that the largest number and the smallest number are one and the same differentiated only by direction, if I could prove that, we could open the door to a new beginning.
