There is an I in "happiness",There is no Y in "happiness",It's an I.
幸福的幸里面是一个“幸”,不是一个“辛”。  或者理解成,Y=Why=为什么,I=我。幸福里面没有为什么,只有我。 
为了成为一名好老师,教育者必须是一位心理学家。
"The truth of a story lies in what it hides, not in what it reveals."
Art is not a mirror held up to reality but a hammer with which to shape it.
The truth is rarely pure and never simple.
