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.
Progress is impossible without change, and those who cannot change their minds cannot change anything.
在危机时刻，真正的领导者通过保持冷静、专注和果断而脱颖而出。
