没有孩子的民族将面临无望的未来；没有树木的国家将面临更加无望的未来。

The world is in a constant state of flux. Nothing remains the same from one moment to the next. You can never step into the same river twice.

成功的关键是坚持和永不放弃。

Gratitude unlocks the fullness of life. It turns what we have into enough, and more. It turns denial into acceptance, chaos to order, confusion to clarity. It can turn a meal into a feast, a house into a home, a stranger into a friend.

I think you have to have an attitude of willingness to accept failure, which is part of innovation.

那些愿意为了安全而放弃自由的人，既得不到安全，也得不到自由。
