Survival Tip #89
Find Things to Fight For
A man who has nothing left to fight for is far less dangerous than the man that has everything to fight for. Finding reasons to live in the Primal Age will be as important as staying alive for those reasons. Times will be tough, you will suffer loss, but you have to find reasons to keep fighting. The more things you have to fight for, the more likely you are to fight hard enough to see them again.

Not forgetting
A man with nothing left to lose is the worse type to engage.
At that point any restraint he had is usually forgotten.
