you can live on 10K/year - anybody can really.
The question is.... Do you want that 10k lifestyle ? Or do you want a better lifestyle ?
It is easier than it looks - just do not own a car, collect recyclable cans for food, buy extremely cheaply, no new clothes and get entertainment from internet, free shows, library books, no illness and be a loner.
I would like a better lifestyle, but if it is the choice between having to work and not having to work, I would sacrifice a lot.
