The mind once enlightened cannot again become dark.

My mission in life is not merely to survive, but to thrive; and to do so with some passion, some compassion, some humor, and some style.

The universe is not only stranger than we imagine, it is stranger than we can imagine.

The world is so unpredictable. Things happen suddenly, unexpectedly. We want to feel we are in control of our own existence.

最终的悲剧不是坏人的压迫和残酷，而是善良人的沉默。
