The only true happiness comes from squandering ourselves for a purpose.

"The colony is the place where the project of a new humanity is to be tested, where the dream of a world without borders is to be realized, where the dream of a world without races is to be realized, where the dream of a world without nations is to be realized, where the dream of a world without classes is to be realized, where the dream of a world without genders is to be realized."

True progress comes when we challenge the status quo and embrace change.

永远不要停止学习，因为世界永远不会停止变化。

If we don’t act now, the next generation will inherit a world with fewer resources and greater challenges.

You have to be thick-skinned in this business.

世界不是一个需要解决的问题；它是一个我们所属的生命体。
