Leaders and teams can learn quite a bit from watching geese work together. Geese fly in the V-formation because they use the lift created by the birds in front of them to make it easier for them to fly. As soon as they fly out of formation, they feel the drag and move back into formation. By doing this, they can fly faster and farther - over 70% farther!
When the leader tires, he falls back in formation and another goose steps up and takes the leadership role. The geese take turns sharing the burden of leadership.
