"You will own nothing and like it" is a half-truth. How can anyone be happy not owning anything at all? You don't have to own anything big like a house or a car, just something that's yours forever and makes you unique.
The "You will own nothing and like it" quote sounds like something your commanding officer would tell you when you're in trouble. Your CO would say to you, "You're going to do X, and you're going to love every minute of it." And you would do X and hate it but not complain about it.
