I once thought that inspirational things inspired people, but I've realized that people are inspired by inspiration itself. Inspiration can be born of many things - a great idea, strong leadership (especially in difficult times), the opportunity to contribute or make a difference, or simply realizing that by taking action you can make things better in some way. As a soldier for many years, I had occasion to encounter circumstances that could quickly demoralize people and whole organizations. It was during those times that I discovered a key that worked time and again to keep people engaged, effective and enthused. The key is the power of perpetual optimism.
