把这一句，留给此刻的你

There is only one optimist. He has been here since man has been on this earth, and that is man himself. If we hadn't had such a magnificent optimism to carry us through all these things, we wouldn't be here. We have survived it on our optimism.

只有一个乐观主义者。自从人类来到这个世界上，他就一直在这里，那就是人类自己。如果我们没有如此乐观的心态来度过这一切，我们就不会在这里。我们靠乐观度过了难关。

— Edward Steichen 爱德华·史泰钦
