把这一句，留给此刻的你
While there is a chance of the world getting through its troubles, I hold that a reasonable man has to behave as though he were sure of it. If at the end your cheerfulness in not justified, at any rate you will have been cheerful.
虽然世界有可能摆脱困境，但我认为，一个理性的人必须表现得好像他对此很有把握。如果到头来你的快乐没有理由，无论如何，你还是会快乐的。
