We were going to die. It was Vietnam 1968. My soldiers and I fought back. We improvised. We adjusted. We quickly learned what we needed to learn. We survived. The Viet Cong's Kill Zone was our biggest threat. So we mastered the concept of the Kill Zone. Later in life I realized that Vietnam had taught us about life. There is always a Kill Zone. But if you know to spot it, you can learn to survive and prevail. Just like Vietnam! Mastering the concept of the Kill Zone is a Mindset that will serve you well!
