一个公司的文化取决于它如何对待最低级别的员工。
A company's culture is defined by how it treats its lowest-ranking employee.
当人们做不到一些事情的时候，他们就会对你说你也同样不能。
The only constant is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be.
Sustainability is the future of quarrying, and we must act now.
The best way to survive in the wild is to stay calm and think clearly.
——〈建国方略之一：孙文学说——行易知难〉，1919年5月20日
