Still Want to Quit?

Somewhere a True Believer is training to kill you. 

He is training with minimal food or water, in austere conditions, training day and night. The only thing clean on him is his weapon, and he made his web gear himself. He doesn't worry about what workout to do - his ruck weighs what it weighs, his runs end when the enemy stops chasing him. This True Believer is not concerned about 'how hard it is'; he knows either he wins, or he dies. He doesn't go home at 17:00; he is home.

He knows only: The Cause."
