科学的美丽在于它让我们惊讶的能力。

"The word is the shadow of the deed."

Optimists tend to interpret their troubles as transient, controllable, and specific to one situation. Pessimists, on the other hand, believe that their troubles last forever, undermine everything they do, and are uncontrollable.

我们内心都有意想不到的潜力，当生活考验我们时才会显现。
