You would adapt rapidly.

I was fired from a city job.

Started hitchiking and living outside. Eventually worked on a fishing boat in the Bering Sea, worked the oil fields in the Dakotas, fought in a civil war in another country, hiked state-long parts of the PCT, hung out with tree-dwelling hippies in the doug-fir forests etc.

I would live that life again in a heartbeat if I didn't have a child to support, which was pretty much the end of my adventures. If you're single you can pretty much work day labor 25% of the year and have plenty enough to live inna-woods. The reason why most 'homeless' people seem so miserable is they are too mentally ill or drug ridden to do some fairly basic things to make their lives living outside 100x better; if you are sober and able bodied and able-minded it is a cakewalk.

You have any write ups? Sounds like quite the interesting life
