Your best bet on survival will be educate yourself on most everything you normally do or have done AND actually put those skills to use. Learn to live life on your own for the most part. Learn to live life in a primitive way so to speak. Do what you can by scratch and that includes growing, raising, canning, dehydrating, smoking, diagnosing and medicating (this would involve scavenging for herbs and plants), first aid, soap making (lye is almost as good as bleach), purifying, etc., etc., The list just goes on and on. It needs to be a mind set for everyone who preps.
