If you're at all familiar with the SCA, one of the three peerage orders is that of the Pelican: http://www.sca.org.au/pelicans/ it awards people for outstanding service (seriously, to get one, you have to have run many events over a decade, and worked damn hard making people happy to get it). You are unlikely to get one unless you consistently, and sustainedly want to serve the needs of others for long period of time.

You strike me as potential Pelican material...

Note: The fact that this community (the SCA) consistently gives accolades for service is, I think, one of the reasons why it is so successful at being a Community.

By contrast, the other two peerages: Chivalry (for sword fighting) and Laurels (for making cool stuff) are both "Look what I did/made" orders... full of heroes (the former more than the latter, in my mind). Which is great and necessary and really cool... but without the Pelicans, the Society as a whole wouldn't exist.

My suggestion: adopt and help sustain a community of rationalists near you.
