Knowledge is represented in the mind as symbolic structures.

Don't let fear stop you from pursuing your dreams.

"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, where the dream of a world without religions is to be realized, where the dream of a world without money is to be realized, where the dream of a world without property is to be realized."

好名声不能轻而易举地得到，荣誉也不能以巧诈树立，君子用身心戴道而行。以身戴行，是一个成语，意为言行合一，用身心戴道而行。

We must balance the need for affordable energy today with the imperative of building a sustainable energy future.

即使没人相信你，也要相信自己。
