一个伟大的企业以合理的价格购买，胜过一个一般的企业以优惠的价格购买。
A great business at a fair price is superior to a fair business at a great price.
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
The only way to do great work is to love what you do.
