1.HAPPINESS REVISITED - Overview

Contrary to what we usually believe, moments like these, the best moments in our lives, are not the passive, receptive, relaxing times— although such experiences can also be enjoyable, if we have worked hard to attain them.
** What were your best moments in your life? 
The best moments usually occur when a person’s body or mind is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile.
**人生中最美好的时刻，文章强调个体的主动性和专注度，但是我觉得身边多数人的描述，似乎大多是与他人互动时获得的，也许这是作者研究的社会群体（体验）差异导致，或者文化差异？暂且存疑。
The optimal state of inner experience is one in which there is order in consciousness. This happens when psychic energy - or attention - is invested in realistic goals, and when skills match the opportunities for action. 
**对中信版翻译存疑，英文强调专注于可实现的目标，技能与行动时机的匹配。中文翻译“只有当精神能量（即注意力）专注与实现目标，行动与机缘又搭配的天衣无缝时，才会出现这种现象。” Skills 的意思没有看到。。。
