This and this are very interesting. It gives me a framework for thinking about:

  • How I lived, rent-free, for years on land I didn't own.
  • Why I don't think about asking for money when I fix someone's computer or help them get something working or host something for them on the web.
  • Why I've not bought land to put my yurt on, and keep being unsure it's a good idea.
  • How contributing to free software isn't just throwing my time away for no return.
  • Why I get to travel to interesting places so frequently and inexpensively.
  • Why I'm housesitting this week.
  • How I get fresh eggs, plant sets for the garden, summer produce.
  • Why I have email in my mailbox offering to buy me a train ticket in Spain.
