It makes you sound unconfident in your ability to execute something.

它让你听上去对你完成某事的能力很不自信。

That tantalizingly precarious balance between confidence in my ability to execute the trick safely and excitement for the unpredictable experience to come.

对安稳完成动作的自信，对即将到来的未知体验的兴奋，这两者之间那种摇摇欲坠的平衡让我欲罢不能。

And of course, you know, I thought that I was—because of the things that I learned and because of the ability to execute what I wanted to do, because of my ability to organize a kitchen, I thought that I was invincible.

当然，你知道，我认为我是——因为我学到的东西，因为我有能力执行我想做的事情，因为我有能力管理一个厨房，我认为我是不可战胜的。
