把这一句，留给此刻的你
As the ancient commander addressed his soldiers before battle, so should the moralist speak to men in the struggle of the era.
正如古代指挥家在战前对士兵讲话一样，道德家也应该在这个时代的斗争中对人们讲话。
A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
There is poetry as soon as we realize that we possess nothing.
当我们意识到自己一无所有时，就有了诗歌。
Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.
我们对自然的观察必须勤奋，我们的反思必须深刻，我们的实验必须精确。我们很少看到这三种方法结合在一起;因此，有创造力的天才并不常见。
Worry doesn't help tomorrow's troubles, but it does ruin today's happiness.
担心不会帮助明天的烦恼，但会毁掉今天的快乐。
