I chose librarianship sort of by a heuristic process of elimination. I considered other careers, but none of them was such a good fit. When it occurred to me to become a librarian, all of the switches clicked into place. It has all the things I really wanted when I was in my twenties and unsatisfied with the paths that I tried. I have since figured out that there are other things about the nature of libraries that initially excited me that I wasn't conscious of at the time of making the choice.
Libraries are at once communitarian and libertarian.
I'm glad to be a part of. The principle of sharing resources allows for decreased consumption, which is good for the soul, the environment, and future generations. I became cynical about rallies, feeling that they were mostly a form of group therapy. I have more positive feelings about them today, and sometimes wish I had the freedom from responsibility that's necessary to pack up and go to a big demonstration somewhere and risk getting arrested. Being involved in PLG and SRRT is a way of having a home among like-minded librarians.
