这是最好的时代，这是最坏的时代。
"Life is the bitch and death is her sister."
不作为的代价远大于行动的代价。
You have to fall before you can fly.
It seems to me that if you or I must choose between two courses of thought or action, we should remember our dying and try so to live that our death brings no pleasure to the world.
The meaning of life lies in the pursuit of truth.
