Fantastic piece! This should be required reading in all high school (or earlier) together with pg's essay "How to Make Wealth" (<a href="http://www.paulgraham.com/wealth.html" rel="nofollow">http://www.paulgraham.com/wealth.html</a>):<p>Kids know, without knowing they know, that they can create wealth. If you need to give someone a present and don't have any money, you make one. But kids are so bad at making things that they consider home-made presents to be a distinct, inferior, sort of thing to store-bought ones-- a mere expression of the proverbial thought that counts. And indeed, the lumpy ashtrays we made for our parents did not have much of a resale market.<p>As he points out, most everyone loses this innate understanding of creating wealth, making stuff, as they grow older. This guy has rediscovered it.<p>Oc course, this would have been impossible without the enabler of shared space, so we should have more of these.
