I lived on the street for a period of time, by choice. It was an eye opener. I didn't have much worry, and happiness is a state of mind. It's very different when one is supporting a household, and income doesn't go far enough to make ends meet. That's my current condition - not poverty, but worry, worry, worry.
What led you to choose living on the street? How long did you do it? Wasn’t it scary? I know, so many questions so little time:)
