Rather than the word career, I prefer to discuss how you make a positive I pact on the world. This could mean raising your children, professional activities, non-profit work, or various other actions you take that impact others. I have found that, at all ages, people want to be needed and play a role in impacting the world.

In my opinion, you have to have a vision for how you add value to others through your product or service. Why do you exist? All of us need a reason to get out of bed in the morning and enthusiastically approach each day. Some people say money is their purpose - - my reaction is that, if money is your purpose, you risk running out steam well before you make a lot of money. Money is an outcome that comes as a result of adding value for a sustained period of time. I encourage people and companies to search for and articulate the vision for why they are doing what they're doing.

Vision and priorities should precede actions. Actions should be judged through the prism of how the firm adds value and the key competencies it seeks to build.

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.

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.

The better strategy is to focus on strengths and surround yourself with people who can complement your skills. However, you have to first do the analysis.

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.
