对自己有信心，能“吃自己的饭”。
一、角色互换的方式对待他人
Deliver to the world what you would buy if you were on the other end.
二、吃自己的饭
We eat our own cooking.
三、追求长期回报
Maximum long- term average return on capital.
四、考虑最坏的情况
We use debt sparingly, never risk what we have and need for what we don’t have and don’t need.
五、把钱种在地里，定期检查
Every $1 of earnings was always worth more than $1?
