The greatest thing in life is to keep your mind young. The great leaders have always stage-managed their effects. Everyone feels that he or she makes a difference to the success of the organization. When that happens people feel centered and that gives their work meaning. In fact, if anything, I am the prod.
Effective management is discipline, carrying it out.
The last is to say thank you. In between, the leader is a servant. If you must be without one, be without the strategy. The price of greatness is responsibility. If you don't choose to do it in leadership time up front, you do it in crisis management time down the road.
