Leading in Turbulence

"The leader's expectations have their strongest and most powerful influence in times of uncertainty and turbulence. When accepted ways of doing things are not working well enough, then a leader's strong expectations about the destination, the processes to follow, and the capabilities of the team serve to make dreams come true. There is no doubt, expectations - high or low - influence other people's performance. But only high expectations have a positive impact - on actions and on feelings about oneself. Only high expectations can encourage the heart." James M. Kouzes and Barry Z. Posner, The Leadership Challenge Third Edition
