I know this because the research is entitled How Backup Plans Can Harm Goal Pursuit: The Unexpected Downside Of Being Prepared For Failure.

我是因为一项研究而知道这些的。该研究被称为《备用计划是如何伤害追求目标的：为失败作准备未预料到的负面效果》。

The researchers confess that having a Plan B makes you feel psychologically more secure.

研究者们承认，B计划使你心理上感觉到安全。

But, and it's a big but: "We propose that the mere act of thinking through a backup plan can reduce performance on your primary goal by decreasing your desire for goal achievement."

但是，这是一个很大的但是：“我们提议，对备用计划的思考将降低你实现目标的渴望，进而降低你最初目标的效果。

There's that word in which so many believe. You have to want to achieve that goal. You really have to want it.

如此多的人相信那个单词。想要实现目标，你确实想要它。

I've known plenty of people, however, who really wanted it, but -- whether through poor execution or annoyingly bad luck -- got bupkis.

然而，我知道很多人确实想要它，但因为糟糕的执行或令人烦恼的坏运气，最后什么也没得到。

The researchers say they executed three studies.

研究者说他们进行了三项研究。
