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.

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.

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.

As a leader, it is often better to ask the right questions and listen than to have all the answers.

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.

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

Every person I meet is struggling with how to understand themselves and reach their full potential. No one has it fully figured out. It is a life long struggle - -there isn't a precise destination or arrival.
