I know of no single formula for success, but over the years I have observed that some attributes of leadership are universal, and are often about finding ways of encouraging people to combine their efforts, their talents, their insights, their enthusiasm and their inspiration, to work together.

Humility must always be the portion of any man who receives acclaim earned in blood of his followers and sacrifices of his friends.

Every leader should have enough humility to accept, publicly, the responsibility for the mistakes of the subordinates he has himself selected and, likewise, to give them credit, publicly, for their triumphs.

Be a great teammate - you learn how to lead, you learn how to influence by the way you interact with your peers, treat them well, help them, help them do a better job.

I would say that I'm blessed with a very, very good executive team that operates, reasonably autonomously, each of the companies.

Every man, every woman who has to take up the service of government, must ask themselves two questions: 'Do I love my people in order to serve them better? Am I humble and do I listen to everybody, to diverse opinions in order to choose the best path?' If you don't ask those questions, your governance will not be good.
