I think that self-discipline has to be accompanied by passion.
People may teach what they know, but they reproduce what they are.
The length and breath of our influence on others are directly related to the depth of our concern for them.
Realizing your potential as a leader is your responsibility.
Personal and organizational effectiveness is proportionate to the strength of leadership.
Leadership is influence, nothing more, nothing less. How do you gain influence from people? You invest in them. How do you invest in them? It starts with giving them time.
