Here is a second resource, the successor of Jacob, creator of ERE, Mr. Money Mustache. This website has the same concept, taken to the same extremes, though he has a more colloquial style. He proclaims to live a luxurious life on 8,000 a year a person (family of three). This includes taking multiple road trips with his family, eating organic foods and other such "luxuries".

Wow, I think that link is the most useful thing I've gotten from this thread; thanks. I've had similar ideas for a while but never knew there was this much info online about it. Their techniques look like they could be very useful for people interested in hardcore professional philanthropy.

Thanks for posting this! Looks quite interesting.
