Since I have children,I try to spend evenings with them sometimes. The rhythm that works best for me is to work a very long day, sleep in the office or near the office (I have a long commute from home to work) then go home early enough the next day to spend time with my children before they go to bed. I am not comfortable with this, but it is the best compromise I have been able to work out. Go home if you have a contagious disease. You should go home if you are thinking suicidal thoughts. You should take a break or go home if you think homicidal thoughts for more than a few seconds. You should send someone home if they show serious mental malfunctioning or signs of mental illness beyond mild depression. If you are tempted to be dishonest or deceptive in a way that you normally are not due to fatigue, you should take a break. Don’t use cocaine or amphetamines to combat fatigue. Don’t abuse caffeine.

以上是在读这本书的时候看到的一段。虽说讲的是如何成为一名程序员，但这样一段文字和我这些时间一直在考虑的问题很是有些关系，不知是碰巧还是其他的原因，让我读到上面这些。我想有必要抄译出来，也算是在思考绳索上打个结做记号：

自我的孩子们出生之后，我便尽量安排出晚上的时间和他们一起度过。现在，我摸索出了最合适自己的工作节奏：先是一整个漫长的白天都在工作，然后在办公室或是就近睡觉(从我家到办公室距离很远)；接下来的那天我会及早结束工作回家陪孩子玩，一直到他们睡觉。我并不觉得这样的安排很舒服，但这已经是我在家庭和工作间能做到最好的权衡了。

所以，如果你得了传染病，就回家去；如果你忙得想要自杀，就回家去；如果你累得想要杀人，就回家去。

同样的，如果你的同事中有人呈现神经错乱或是一定程度上的精神问题，你也应该劝他/她回家。

如果疲劳让你开始变得不诚实，开始试着隐瞒事实，那么你应该休息一会了。

不要试图用可卡因或是安非他命来提神。

不要滥用咖啡因。
