A little critical, analytical thinking is a good thing. Without doubting ourselves sometimes we'd find it difficult to make good decisions.
有一些批判性、分析性思维是一件好事。有时候，不自我怀疑的话，我们就很难做出好的决定。

Too much doubt, though, can stop us living our lives to the full. Some people can never make up their minds about their careers, their love lives or much else.
但是，太多的怀疑也会让我们的生活不得圆满。有些人就是难以对他们的事业、爱情或者其他许多东西做出决定。

The problem is that we can never really know what the outcome of our decisions will be, that's the nature of life. But the person who never takes a risk, however small, never gets anywhere. At some point, after a little looking, you've got to leap.
问题是，我们从来都不会真正清楚我们做的决定会带来什么样的后果，这就是生活的本质。然而，那些连一个小小的风险都不敢冒的人，是什么都不会得到的。有时候，稍作观望之后，你就应该奋力一搏。

Doubt your doubt
怀疑你的怀疑

This is a fascinating counter-intuitive case when lack of confidence in your own thoughts. Perhaps learning to doubt the doubt more will offer one way of helping to escape from some of the crippling effects of excessive self-doubt. It is interesting that doubting your doubt can work to dispel the original doubt.
当你对自己的想法不够自信的时候，怀疑你的怀疑就是对付“怀疑”这种本能反应的绝招。也许，学会怀疑“怀疑”能给我们提供多一种对付过度怀疑的方法。有趣的是，怀疑你的怀疑恰恰是驱散你原始怀疑的有效方法。
