S.T.O.P.: Stop, Think, Observe, Plan
When you find yourself in a survival situation, the most important tool is your brain.
Stop when you realize you've got a problem. The first thing to do is admit to yourself that you are in trouble.
Think about what you need to do to survive.
Observe the area; and look for shelter, fuel, etc.
Plan how you are going to use your survival kit and your other available resources. Don’t wait until dark to plan!
Remain calm. Think clearly. Use the tools you have available to you. You now have three priorities: shelter, fire, and signal.
