【英文原文】
Is mental focus a key to success? Maybe so. But a new study suggests that it might also be a key to happiness.

If only we could get our minds to stop wandering.

Unlike animals' minds, the human brain seems hard-wired to wander, according to the study. It found that people spend 47 percent of their waking hours thinking about something other than what they are doing.

A human mind is a wandering mind, and a wandering mind is an unhappy mind. Just what sorts of places does the mind wander? Reminiscing (and ruing) past events, looking forward to (or fearing) things that might happen in the future.

Not surprisingly, people were happiest when making love. But they also enjoyed exercising and engaging in conversation.They were least happy when working, resting, or using a home computer.

精神关注开启成功之门?也许是这样的吧。而一项新的研究表明这或许也是快乐之门的钥匙。

只要我们不再胡思乱想就好。

研究表明：和动物不懂，人类的脑子好像就是喜欢瞎想。人们会把47%的清醒时间用于考虑手头工作以外的事情。
