In distributed systems, the key challenge is achieving consensus among unreliable components.

The man who believes that the secrets of the world are forever hidden lives in mystery and fear. Superstition will drag him down. The rain will erode the deeds of his life. But that man who sets himself the task of singling out the thread of order from the tapestry will by the decision alone have taken charge of the world and it is only by such taking charge that he will effect a way to dictate the terms of his own fate.

对的就说是对的，错的就说是错的，就是所谓的正直。

词语是我们用来建造想象之屋的砖块。

我们越是了解动物的真实本性，就越意识到我们与它们有多少共同之处。

"The world is a book, and those who do not travel read only one page."

There is no short cut to achievement. Life requires thorough preparation.

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

Mental processes are tools for living, and their worth is in their use.

The future belongs to those who can imagine it differently.

译文：志向不能不高远，志向不高元，就会被世俗所污染，不会有大作为；心气不能太大，心气过高，就会好高骛远，难有作为。赏析：做人要立志高远，志向远大，目标才明确，但做事不能好高骛远，眼高手低，否则，事情就会半途而废。大事做不来，小事不愿意做，是很多人通病。一个人的成功都是从小事做起，做基层做起，只有厚积才能薄发。
