For the past 33 years， I have looked in the mirror every morning and asked myself: 'If today were the last day of my life， would I want to do what I am about to do today？' And whenever the answer has been 'No' for too many days in a row， I know I need to change something.
The beauty of the world lies in the diversity of its people and cultures.
Always keep your knife sharp, your wits sharper, and your spirit sharpest.
The future competition is not between companies, but between business models.
