译文：人生不能过于安逸闲散，有了可以不断追求的事业，才能收回安逸之心。日用花费必须要节俭，只有杜绝奢靡，才能彰显勤俭的美德。赏析：生于忧患死于安乐。逸豫可以亡身，忧劳可以兴国。一个人过于安逸，就会无所事事，丧失斗志。一粥一饭当思来之不易，半丝半缕恒念物力维艰。

Conflict is the gadfly of thought. It stirs us to observation and memory. It instigates to invention. It shocks us out of sheeplike passivity, and sets us at noting and contriving.

The only way to survive is to take care of each other.

探索计算复杂性是一段进入未知的旅程，每一次发现都会打开新的门。
