痛苦的源头是无知。
The fountain of content must spring up in the mind, and they who have so little knowledge of human nature as to seek happiness by changing anything but their own dispositions will waste their lives in fruitless efforts.
如果你掉进了黑暗里,你能做的,不过是静心等待,直到你的双眼适应黑暗。
I'm not afraid of storms, for I'm learning how to sail my ship.
