My uncle told me this when I was a bit younger, and it's something I've always remembered. I'm not sure if my father told me this as a child, but I was at least raised with this mentality. I know this because he made sure I knew how to do things like fix a small engine, music, computers, etc..

Yeah, every man should have a certain set of skills like starting a fire, fish, shoot a gun, and a lot can me found here, but thats not really what I'm talking about.

I'm talking about having skills that could provide for you and yours in modern society. Are you an electrician, plumber, mechanic, musician, handy-man? Its amazing how many people spend 12 years in public schools and four years in college to come out into the world with zero skills. So ask yourself, what are my skills?
