Self Sufficiency, not necessarily for Self

Well I was thinking about this whole self sufficiency thing today. Actually yesterday, but who is keeping track? As much as you may strive for self sufficiency you almost necessarily need others to help you or join you in your quest. Now, I am not saying you can not go the distance yourself, but let's look at a couple of examples.
What good would it do to be totally self sufficient? If you were the ONLY survivor left in the world, I guess that could be beneficial. If you and some other like minded people survive a disaster of some kind or the society you live in collapses into disorder and chaos and you and your like minded friends have already shared your desires to be 'self sufficient', you then know who you can count on to help you when you need help and who you can go to for extra protection, advice, security, food, supplies and strategies. Where I live, many of my neighbors share the ideas of freedom, less government, country living, self sufficiency, food production and storage, guns, God, and survival. I know this because we all got together for a barn raising of sorts several months ago, around Halloween. We don't get together often, as a matter of fact, can't remember another time we have all gotten together. We all know of each other. We all hear about one another through the local grapevine. We all knew we shared similar interests from what we heard from others. We finally got a chance to get together and see each other eye to eye. That makes a huge difference. You look a man in the eye and talk to him. You know his intentions when he speaks. You understand from the spoken words and the unspoken signs, what is meant or implied when he speaks. You shake hands, size each other up both physically, mentally, spiritually, and know where each other stands. You better understand the man's soul and spirit. You realize he is a man you can count on. He has a family, he has stuff, he has property, guns, horses, vehicles, dreams and desires like you do. You know then, you can count on him and you are willing to watch his back too.
So yeah, you can go it alone. Why would you?
We all decided the little black bear spotted on the hill was fairly harmless at this point. If he got to bold we would have to kill him, legally of course. We talked about projects we might need help with over the coming months. We talked about each other and our spouses. Checked on our friend who lost his wife far too soon, far to young. He says he is doing fine. We all know he is just doing. Surviving. We knew he was happy to have help with building his steel building and to have us all there at the opening. We all know he will be there on our projects, when he can, when we all can. What a life. Welcome to 'self sufficiency'.
