The people who survived the sword found grace in the wilderness, the people's of Israel when it went to find its rest. And we usually call it the “will to survive” although you might call it “attitude” just as well. This basically means that, if you do not have the right attitude, you may still not survive.
And then, why would 21st centuries mankind's need to learn to "survive" in today's world?
Generally, I illustrated in teaching course format, as below:
01. Requirements for Survival
02. Survival Tools
06. Core Values
11. Traps and Snares
14. Tools and Equipment
