The secret to living is giving.
Mathematics is not just a tool; it is a way of thinking.
过去并非死寂之地，穿越它绝非徒劳之举。
要发出紧急信号，使用“重要的事情说三遍”的“三”法则；三次呼喊、三声喇叭或三声哨声。
To transform is to give new life.
在遇到梦中人之前，上天也许会安排我们先遇到别的人；在我们终于遇见心仪的人时，便应当心存感激。
"Theologians talk about a prevenient grace that precedes grace itself and allows us to accept it. I think there must also be a prevenient courage that allows us to be brave - that is, to acknowledge that there is more beauty than our eyes can bear, that precious things have been put into our hands and to do nothing to honor them is to do great harm."
