We often think that when we have completed our study of one we know all about two, because "two" is "one and one." We forget that we still have to make a study of "and."
我们常常认为，当我们完成了对一的学习，我们就知道了关于二的一切，因为“二”就是“一和一”。我们忘记了我们仍然要研究“和”。
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。
Remember that the happiest people are not those getting more, but those giving more.
记住，最幸福的人不是那些得到更多的人，而是那些付出更多的人。
To travel hopefully is a better thing than to arrive, and the true success is to labour.
怀着希望去旅行比抵达目的地更愉快;而真正的成功在于工作。
