The most impressive thing about this improvement in performance was that it did not come from a major process change or an advance in technology. Instead, it came through a leadership principle that has been around for ages: Simple.
A leader must care about the troops, but at the same time the leader must complete the mission, and in doing so there will be risk and sometimes unavoidable consequences to the troops.
Although discipline demands control and asceticism, it actually results in freedom. When you have the discipline to get up early, you are rewarded with more free time.
