我相信教育改变世界的力量。

The most valuable resource in agriculture is not the crop, but the people who grow it.

The only constant in life is change, and we must embrace it.

The truth is: the natural world is changing. And we are totally dependent on that world. It provides our food, water and air. It is the most precious thing we have and we need to defend it.

I don't believe in regrets. Regrets are a waste of time. They're the past crippling you in the present.

改变是困难的，但对于进步是必要的。
