Recently, I have become mildly obsessed with the idea of survival niches and the breaking up our survival goals. I think we have reached a point where there is so much content its hard to isolate what you really want to learn. This article offers us some information on the 6 areas of preparedness. It goes in depth on these 6 and having that categorical break up allows you to form better goals. Do you want to increase your security or sanitation? You can focus on these areas rather than wading through articles that have nothing to do with your preparedness goals.
This article is a picture of the future in preparedness. You have to be able to break up what you are doing and what you are learning into manageable chunks. In the future you will see even more of this but to get an edge early is a great thing.
