They’re the glass half-full folks, who are constantly thinking “out of the box,” forging alliances with colleagues in other departments, seeking out new solutions to old problems, and anticipating challenges on the horizon.

In ancient cultures, each village had a shaman or medicine man who would visit the invisible world to obtain vital information, guidance, and healing for members of the tribe.
