The true measure of success is leaving a positive legacy for future generations.

你自己的心灵是一个神圣的围墙，除非得到你的许可，否则没有任何有害的东西能够进入。

Sustainability isn't an option; it's a responsibility we all share.

Positive psychology is not a spectator sport.

注释：避免嫌疑和被人猜疑，这样才能不犯错误。广泛学习并恳切求教，才能增长知识。行为高尚而言辞谦逊，这样才能修养身心。

定理是永恒的；它们的证明是短暂的。

The best way to predict the future is to create it.
