生与死的界限至多是模糊不清的。谁能说清一个在哪里结束，另一个在哪里开始？
The boundaries which divide Life from Death are at best shadowy and vague. Who shall say where the one ends, and where the other begins?
Imagination is more important than knowledge.
出自北齐·颜之推《颜氏家训·勉学篇》。秉，持、拿。犹，还。贤乎，胜于。少年时代就好学，就像是早上初升的太阳之光；老来才知道虚心向学，就像是拿着蜡烛走在暗夜中。尽管如此，还是比闭着眼睛什么也看不到要强多了。意在鼓励人们时刻不忘学习上进，如果错过学习的最佳时机，努力追补，仍然是精神可嘉的表现。
Grit is passion and perseverance for very long-term goals.
