Sun Tzu taught that the core of any strategic position is its philosophy. For an individual, your philosophy includes what you see as the meaning, purpose, and rules of your life. For an organization, this shared sense of meaning, purpose and rules brings people together into a shared goal. Clear, strong philosophies that reflect the proven principles of human progress are the basis for both personal and organizational success. The willingness to abandon a philosophy for short-term, "practical" reasons almost always results in disaster in one form or another.
