It's fascinating to read about people like http://earlyretirementextreme.com/ who choose frugality over work
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".
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
