"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers."

Memory is a wound that never heals, and literature is the bandage we put on it.

Joy sparks the urge to play, interest sparks the urge to explore, contentment sparks the urge to savor and integrate, and love sparks a recurring cycle of each of these urges within safe, close relationships.

今天不努力劳动耕种，明天就没有财富货物。

Write a program as carefully as you write a letter.

你必须相信过程并相信自己。
