I don't know your interests/background in school but you reminded me I have a degree in sociology. I would take your interests and look at scholarships, work/studies (the travel :-) Have you ever read Louis L'Amour's autobiography http://www.louislamour.com/nonfiction/index.html Education of a Wandering Man? It's old enough your library probably has it. He had no education, was a teen, and just left home and had at it It's one of my favorite/more inspirational autobiographies.

You clearly enjoy reading certain subjects and would like to read more; so, a goal would be to come up with ways to get to read/study more :-) Do an analysis of the books your public library has on one of your subjects of interest and send a letter making recommendations to the library systems' head librarian? LOL How is that for "more specific"?
