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.

The most important thing in life is to learn how to give out love, and to let it come in.

Always stay curious about new technologies, but be wary of hype.

这是数着别人契上的齿数，而以为自己很富有。 

我愿你快乐，即使你的快乐不再是因为我。
