Instead of buying new things, we find old items and bring 'em back into functioning life. It's one part handycraft, one part DiY, and comes from thinking past the end of industrial-petroleum culture:
[L]earn skills that could well become income sources in the not too distant future; as I’ve suggested more than once here, salvage trades – that is, anything that involves taking the leftovers of industrial civilization and turning them into something that people need or want – will likely be among the major growth industries of the next century or two, and the ground floor is open for business right now...Personally, I (Bryan) have a lot to learn here. I don't buy stuff, generally, unless I can help it. But I don't know anything about making old machines work. Cars, sewing machines, refrigerators, power saws, farming equipment: where do I start schooling myself, and how?
