You never do arrive at a destination. You have to work at it and take ownership of the process. What resonates at age 25 is likely to change by age 35 and 45. The process never ends. Realizing this has been a big breakthrough for me.

Authenticity is critical to leadership. That means trying to be yourself - this involves some self-disclosure, admitting what you don't know and being willing to ask questions.

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.

Screening out peer pressure and conventional wisdom. It is so powerful, that most of us aren't even aware of how much it is influencing our decisions.

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.

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.
