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.

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.

Without strong visionary leadership, no strategy will be executed effectively.

If you're the smartest person in the room, it can sometimes be hard to learn to delegate - the person to whom you're delegating will do the task worse than you would - and it will annoy you!

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.

Change efforts happen when a firm is out of alignment with achieving its vision. If the organization has broad buy-in on a clear vision, the need for change becomes much clearer. It also helps to over-communicate what you're doing and why you're doing it. Lastly, the leadership needs to spend as much time on "how" changes are being made and "what" changes are being made. Human beings are involved and there are winners and losers.

Passion is the rocket fuel that helps you perform at your best. It helps you get through bad days, injustices, hardships and disappointments. It is hard to perform at a high level for a sustained period of time without passion for what you're doing.
