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.

We have all had injustice happen to us. It often shapes our failure narrative. For example, maybe you were fired and not you don't trust colleagues as easily in the future. You may not overcome injustice but you need to be aware of how it affects you today. You can't avoid injustice but that doesn't mean you need to be a prisoner of it.

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.

I like films about people who figured out what they believed and had the guts to act on it in a way that added value to others. So, there are lots of movies that have characters who did that. I'll pick an odd one - Stranger Than Fiction because I really liked the movie - particularly the offbeat cookie maker. You'll have to see the movie to see what I mean. The movie also reinforces that you can be the author of your own script.

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.

Great companies create an environment in which employees act like owners. They do this through clear communication, articulation of clear vision and priorities, coaching and openness to debate/discussion. I would argue that this type of environment helps people to be at their best - and helps the company to be at its best.

Business and leadership is about the future. What worked five years ago is unlikely to work tomorrow.
