The day you join the military is the day you stop being an individual. In the military, “being an individual” is such a bad thing that it’s actually an insult, especially in recruit training. Whether you’re in the military for four years or 40, the work you do becomes your identity. Pilot, grunt, clerk; it’s not just your job description: It’s who you are. If you’d asked me to describe myself while I was in the military, the first words I’d have said were “Marine” and “pilot.”
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
