CIJS,
I think that learning mathematical proofs is one of the most rewarding endeavors that I have ever tackled. In particular, I'm strongly considering teaching myself real analysis (I've already started reading Introduction to Real Analysis by Michael J. Schramm): the material is awesome and the ideas and concepts seem so cool, despite the fact that they are very challenging and will give even the brightest of minds a run for their money.
