My life story as an adult geek.
Sound hokey? As a youth, I read books. Some would call them Christian pop-psychology. Before that I read normal psychology books looking for anything that would help me overcome my social awkwardness or disorders–something that would tell me the things that seem obvious to everyone else but me–stuff people seem afraid to tell me, and if I were to ask, they would say “Go ask your parents or someone else”.
So, I took matters into my own hands and found that other friends did the same thing. We would all read a book we thought was awesome and we would share it with each other. Or we would learn a new concept in psychology.
