I don't know if it will happen.
Having fruit orchards, crop fields, and chickens are very feasible. Going completely self-sufficient is way out there though. Property taxes is one big issue. And god forbid a medical emergency happened... oi. It's probably more of a dream than anything - but I'm gonna try to get it to happen. I know some people do it.
I'll be happy to step out of my house and see acres of MY land though. And to see MY apple orchard. MY sweet peas. MY tomatoes. MY potatoes. MY carrots. To see my future daughter or son experiencing the beauty (and bounty) of life from a much more down-to-earth upbringing.
Farming is in my blood; I don't think anything would make me more proud. Self-sufficiency would just be the greatest echelon I could reach.
My other life goal is to stay with my wife and make our marriage work. With the high divorce rates I think making it a point to stay together for life is really important.
