The following quotes are from the first chapter of Warfighting by the U.S. Marine Corps. They come from the first chapter, which is called "The Nature of War". These ideas offer a direct parallel to my concept of business and/or entrepreneurship.
1. Replace "war" with "business
"Since war is a fluid phenomenon, its conduct requires flexibility of thought. Success depends in large part on the ability to adapt-to proactively shape changing events to our advantage as well as to react quickly to constantly changing conditions."
"War is shaped by human nature and is subject to the complexities, inconsistencies, and peculiarities which characterize human nature."
2. Replace "war" with "entrepreneurship"
"War is an extreme trial of moral and physical strength and stamina. Any view of the nature of war would hardly be accurate or complete without consideration of the effects of danger, fear, exhaustion, and privation on those who must do the fighting."
"Human will, instilled through leadership, is the driving force of all action in war. No degree of technological development or scientific calculation will diminish the human dimension in war.
3. Replace "war" with "business" or "entrepreneurship"
"An even greater part of the conduct of war falls under the realm of art, which is the employment of creative or intuitive skills. Art includes the creative, situational application of scientific knowledge through judgment and experience, and so the art of war subsumes the science of war."
"We thus conclude that the conduct of war is fundamentally a dynamic process of human competition requiring both the knowledge of science and the creativity of art but driven ultimately by the power of human will. "
