To be really happy and really safe, one ought to have at least two or three hobbies, and they must all be real. It is no use starting late in life to say: “I will take an interest in this or that.” Such an attempt only aggravates the strain of mental effort. A man may acquire great knowledge of topics unconnected with his daily work, and yet hardly get any benefit or relief. It is no use doing what you like; you have got to like what you do. Broadly speaking, human beings may be divided into three classes: those who are toiled to death, those who are worried to death, and those who are bored to death. It is no use offering the manual labourer, tired out with a hard week’s sweat and effort, the chance of playing a game of football or baseball on Saturday afternoon. It is no use inviting the politician or the professional or business man, who has been working or worrying about serious things for six days, to work or worry about trifling things at the weekend.

It may also be said that rational, industrious useful human beings are divided into two classes: first, those whose work is work and whose pleasure is pleasure; and secondly, those whose work and pleasure are one. Of these the former are the majority. They have their compensations. The long hours in the office or the factory bring with them as their reward, not only the means of sustenance, but a keen appetite for pleasure even in its simplest and most modest forms. But Fortune’s favoured children belong to the second class. Their life is a natural harmony. For them the working hours are never long enough. Each day is a holiday, and ordinary holidays when they come are grudged as enforced interruptions in an absorbing vocation. Yet to both classes the need of an alternative outlook, of a change of atmosphere, of a diversion of effort, is essential.

要想获得真正的快乐与安宁，一个人应该有至少两三种爱好，而且必须是真正的爱好。到晚年才说“我对什么什么有兴趣”是没用的，这只会徒然增添精神负担。一个人可以在自己工作之外的领域获得渊博的知识，不过他可能几乎得不到什么好处或是消遣。做你喜欢的事是没用的，你必须喜欢你所做的事。总的来说，人可以分为三种：劳累而死的、忧虑而死的、和烦恼而死的。对于那些体力劳动者来说，经历了一周精疲力竭的体力劳作，周六下午让他们去踢足球或者打棒球是没有意义的。而对那些政治家、专业人士或者商人来说，他们已经为严肃的事情操劳或烦恼六天了，周末再让他们为琐事劳神也是没有意义的。

也可以说，那些理性的、勤勉的、有价值的人们可分为两类，一类，他们的工作就是工作，娱乐就是娱乐；而另一类，他们的工作即娱乐。大多数人属于前者，他们得到了相应的补偿。长时间在办公室或工厂里的工作，回报给他们的不仅是维持了生计，还有一种强烈的对娱乐的需求，哪怕是最简单的、最朴实的娱乐。不过，命运的宠儿则属于后者。他们的生活很自然和谐。对他们来说，工作时间永远不嫌长。每天都是假日，而当正常的假日来临时，他们总是埋怨自己所全身心投入的休假被强行中断了。不过，有些事情对两类人是同样至关重要的，那就是转换一下视角、改变一下氛围、将精力转移到别的事情上。确实，对那些工作即是娱乐的人来说，最需要隔一段时间就用某种方式把工作从脑子里面赶出去。
