The article Man in the mirror: two principles for better leadership, from the Australian Institute of Management does not handle leadership from an innovative angle but as a reminder of two basic pillars which probably make the difference between a leader and a successful leader.
The first is about the importance of leading and listening to yourself. If you don´t, chances are that no one else does either.
The second is about your behaviour. As the leader you are the example. By acting the way you would like your team to act, they will because they are affected by their leader´s conduct.
