Hi, I had the same feeling as you (when I was 38) and I started a blog: http://fermatslasttheorem.blogspot.com http://fermatslasttheorem.blogspot.com I started with a sketch of the historical approach to Fermat's Last Theorem (Diophantus, Euler, Gauss, etc.) and I tried to resolve all proofs down to postulates. I would recommend finding an area that you are interested in and then finding a famous problem. My favorite books are: * Euler: Master of us all * Euclid's Elements * Hardy and Wright: Introduction to a Theory of Numbers * Jonathan Stillwell: Yearning for the Impossible * Ash and Gross: Fearless Symmetry * Jean-Pierre Tignol: Galois' Theory of Algebraic Equations * Edwards: Fermat's Last Theorem/Galois Theory I've been doing it now for almost three years and it's really worked out well for me and surprisingly, I am getting around 11,000 unique visitors to my site every month. Glad to see all the responses to your comment. :-) -Larry
