A scientist’s greatest tool is an open mind.

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.

我不知道我想要什么。我反复无常、不坚定、被动；我喜欢不确定、无边界，以及持续的不确定性。

最好的投资往往是那些在当时看起来最疯狂的。
