相信我，这世上没有“他们”。（U2《Invisible》的歌词：“There's no them / There’s only us”）

Technology in forestry should serve sustainability, not just efficiency.

The safest way to try and get what you want is to try and deserve what you want. It’s such a simple idea. It’s the golden rule so to speak. You want to deliver to the world what you would buy if you were on the other end.

True courage is not the absence of fear, but moving forward in the face of fear.

爱不是占有，而是欣赏。

自由的功能是解放他人。
