Finally, there is the rule of happiness. Happiness is a habit. I was taught to cultivate it. A big stomach-ache, or a big heart-ache, can interrupt happiness, but neither can destroy it unless I permit. My mother simply wouldn't have unhappy faces moping about the place. If it was stomach-ache, she does it. If it was heart-ache, she administered love and understanding and lots of interesting things to do, and soon the sun came out again. Even the heartbreaks that can't really be mended, even those seem to yield to the habit of finding happiness in doing things, in love and in the memory of love. I hope I never lose that habit either. It would be like putting out the light.

最后，还有幸福法则。幸福是一种习惯。我学会了去养成这种习惯。剧烈的胃痛与心痛都会阻碍幸福，但没有我的允许，它们绝对无法破坏幸福。母亲不愿意看到家中有人闷闷不乐。如果有人胃痛，母亲会给他吃药；如果是心痛，她会给予爱和理解，并做很多有趣的事让他忘记痛苦，重新展露笑颜。即使心碎了，无法再修补，即使有人习惯在工作、爱与爱的回忆中寻找幸福，我也希望我永远不会将这一习惯丢弃。拥有它，就仿佛点亮了生命的明灯。

So I learned to live, by the great laws, and these little rules of thumb. I wouldn't take a million dollars for any one of them, or a million times that for the years at home that taught them to me.

因此，我学会了生活，并遵循着伟大的定律与这些琐碎的经验法则。即使给我100万美元，也换不去它们中的任何一个；或者即使给我无尽的时间，也无法交换那些让我懂得这些法则的家中岁月。
