I'm reading and being inspired by Robert E. Quinn's book, "Building the bridge as you walk on it: A guide for leading change." Not a weekend read (too deep for that) as there are many thought-provoking leadership concepts to digest. One so far really stood out, and that is the concept of appreciative leadership, as quoted here.
"It could be argued that all leadership is appreciative leadership. It's the capacity to see the best in the world around us, in our colleagues, and in the groups we are trying to lead. It's the capacity to see the most creative and improbable opportunities in the marketplace. It's the capacity to see with an appreciative eye the true and the good, the better and the possible."
- David Copperrider (quoted in Creelman, 2001).
