The vision must be realistic - it has to be based on clear distinctive competencies. Again, what would the world lose if you didn't exist? A vision is very powerful because it gives you a basis to judge every action you take. Every action should be viewed through the prism of whether it furthers the vision.

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.

I loved my career at Goldman Sachs. I believed in business principle number 1: if the client succeeds, our own success will follow. This principle formed the basis for my career and my leadership style.

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.

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.

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

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.
