Reaching your potential is a disciplined process. Like losing weight or getting in shape - there is no final destination and it requires you to dust off atrophied muscles. You have to work at it. If you do, I think you will dramatically improve your leadership.

Why do leaders fail? Isolation and inability to learn. They are afraid to express doubt, admit vulnerability or seek advice from subordinates. Leaders must actively work to seek feedback and a reality check. They must be open to asking questions and framing issues. As the world becomes more complex and global, the risk of isolation becomes greater. The need for leaders to be open to learning becomes greater. Great leaders will need to ask the right questions and balance inquiry with advocacy.

You're changing, the world is changing, and your hopes and aspirations are regularly being updated. That's why I say this is a life long struggle - for everybody.

Education has been critical. First at Kansas and then at Harvard Business School. It helped me build the confidence that I could go out and do things in the world. It taught me to put myself in the shoes of a decision maker and figure out what I would do if I were in his/her shoes. This is why I am a big believer in education as a foundation for reaching your unique potential.

Great companies create an environment in which employees act like owners. They do this through clear communication, articulation of clear vision and priorities, coaching and openness to debate/discussion. I would argue that this type of environment helps people to be at their best - and helps the company to be at its best.

There is usually a clock in our heads regarding decisions we make and the course of our lives. Sometimes this clock is helpful in that it get us to move rather than put off key actions. Other times, it creates us false sense of urgency that can cause us to overreact, lost patience and make poor decisions. In raising this issue in my book, I want people to be aware of the clock in their heads and question whether that clock is helping or hindering the quality of each particular decision.

There's a step that leaders need to take; they've got to understand themselves.
