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。
Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge. That's what we're doing.
想象一下这样一个世界:地球上的每一个人都可以自由获取人类所有知识的总和。这就是我们正在做的。
Change the changeable, accept the unchangeable, and remove yourself from the unacceptable.
改变能改变的，接受不能改变的，远离不能接受的。
