如果你想改变世界，先从改变思维方式开始。

译文：人必须在事情上磨炼，才能立得住;才能做到安静时也安定，行动时也安定。

质量不是愿望；它是一种承诺。

如果你想拥有从未有过的东西，你必须愿意做从未做过的事。

Our heroes are human heroes. That's a very new situation. Most other societies have had, right at their center, the worship of something transcendent: a god, a spirit, a natural force, the universe, whatever it is -- something else that is being worshiped. We've slightly lost the habit of doing that, which is, I think, why we're particularly drawn to nature.

The world is a stage, but the play is badly cast.

所有科学的起源在于渴望了解原因，而所有伪科学与欺骗的起源则在于宁愿接受虚假原因也不愿承认无知。
