During mountain and cold warfare training in Norway, these Royal Marines undergo a unique training ritual. Without spoiling the video, I will recommend listening for these words from the Royal Marine Instructor Cadre:

“Control, Confidence, Humor, Character.”

Training scenarios such as this one develop these traits: Control – Confidence – Humor – Character.

Note: Do not underestimate the value of humor in dealing with difficult circumstances. It often reveals latent ruggedness and  sustainability.
