最好的投资是投资于自己行业的工具。

解析：君子要求的是自己，小人要求的是别人。

"The only true voyage of discovery, the only fountain of Eternal Youth, would be not to visit strange lands but to possess other eyes, to behold the universe through the eyes of another, of a hundred others, to behold the hundred universes that each of them beholds."

人生は、自分で選んだものではない。でも、選んだものだ。
