I'm not an anarchist (even if I'm somewhat sympathetic), but I gotta tell you, one of the most profound lessons I learned in my life was from offline anarchists:
If you see a problem in your community, or an opportunity to make things better, just get a few passionate friends together and do it, don't wait for some institution to come knocking and asking for your help.
Very cheesy, perhaps, but it really changed my approach to some things in life, including many things in my academic life. Thanks, you idealistic anarchists!
