It bears repeating: you don't have to be good at everything.

Step one is to take ownership of figuring strengths ans weaknesses out. It starts with writing them down but, to take ownership, you have got to seek feedback of those who directly observe you - this is scary and uncomfortable for many people. It's no fun to hear negative feedback and most people don't want to stick their necks out to give it to you. So, you have to ask.

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.

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.

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

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.

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.
