Sustainability is not an option; it's a necessity for the future of mining.

翻译：人无完人，管理者的智慧不在苛求完美，而在将合适的人放在合适的位置，让短板变跳板。

The only time you fail is when you stop trying.

Don’t take it personally when someone turns you down. Assume they are like you: busy， occupied， distracted. Try again later. It’s amazing how often a second try works.

我认为我们在沉默中、在未说出口的话中，已经沟通得足够好了。
