快乐是一种感觉良好的状态，而意义则来自于以更大的方式为他人或社会做贡献。

While being happy is about feeling good, meaning is derived from contributing to others or to society in a bigger way.

一种与美好经历有关的气味会带来快乐，而一种恶臭或与糟糕的记忆有关的气味可能会让我们厌恶地做鬼脸。

A scent associated with a good experience can bring a rush of joy, while a foul odour or one associated with a bad memory may make us grimace with disgust.

youdao

我们如用一种坦白的、好奇的、富于冒险性的心胸去维持这个探索精神，则这种寻求行为便永远是一种快乐，而不是痛苦了，我们应该舍弃那种规定的、划一的、被动的强记事实方法，而将这种积极的滋长的个人快乐定为理想目标。

Instead of the measured, uniform and passive cramming of information, we have to place this ideal of a positive, growing individual pleasure.

There's in those images, I think, a kind of utopian promise that the familiar, ordinary pleasures of rural life can be recaptured in a new society of plenty.

在这些图片中，我认为有一种乌托邦的希望,对乡村生活熟悉而平凡的快乐的希望,能在一个自足的新社会里重新得到快乐的希望。
