There are principles that govern human effectiveness - natural laws in the human dimension that are just as real, just as unchanging and unarguably there as laws such as gravity are in the physical dimension.
Stephen CoveyThe personal power that comes from principle-centered living is the power of a self-aware, knowledgeable, proactive individual, unrestricted by the attitudes, behaviors, and actions of others or by many of the circumstances and environmental influences that limit other people.
