And, the situation may be sad, perplexing, or maddening enough to cause you to swing and miss.

而且，情况也许是悲伤的，复杂的，让你抓狂，摇摆不定甚至错过。

In these neutral times, when we are neither ecstatic nor extremely sad, the slightest change in attitude can swing our happiness balance drastically in either a positive or negative direction.

在这些不甜不苦的日子里，当我们既没有狂喜也没有极度悲伤，态度的细微变化就可以使你的快乐在积极与消极之间剧烈的摆动。
