Survivalists develop their skills in order to operate efficiently in any manner of situation.
The true survivalist is able to accept their surroundings and evaluate their situation in a relaxed and rational manner. This enables them to think clearly and develop ongoing strategies to improve their situation.

Take a chill-pill and learn to relax. You'll feel better - trust me.
