During my military survival training, the best advice was to watch for your own mistakes. Aside from the sudden catastrophic event (crash or whatever) many survival situation are self-induced. They are the result of a series of mistakes. Small mistakes. Any of which, alone, would be hardly noticed.
The good sergeant said something to the effect of… Watch yourself carefully. When you make your first mistake take that as a warning. Resolve the issue and then be on guard for the next mistake. When you discover the second, sit down and think about things. Go slower, be very cautious. If you find a third mistake, then STOP. Think about your situation as though your life depended on it, because it probably does.
His example was driving in a remote area. You make a wrong turn. (mistake one) you notice it and decide to turn around. In your haste, you get stuck, mistake two. You get the idea.
The human factor is always the most important part of any difficult situation. It is the time when training and attitude become the deciding factor. But one cannot generate training and attitude when stuck on a deserted road. It comes only with long and dedicated awareness to improving yourself.
