仅仅做到我们的最好是不够的，有时候我们得达到要求。
The best ideas often come from unexpected places.
Every piece of plastic we produce should have a clear path to reuse or recycling.
我喊出我野性的狂叫，站在世界屋脊上。
I don't need a reason to be happy. I choose to be.
重要的不是你击打得多用力，而是你能承受多大的打击并继续前进。
The world is a great clock, and we are the hands.
