句子结构紧凑，使用 'will only diminish' 强调了焦虑带来的负面因果后果，逻辑清晰。
There is a Jewish proverb: “Only one kind of worry is justified: worrying about worrying too much.” This statement is entirely correct. Worry is futile; it merely causes you to spin in circles only to return to where you started. When you feel anxious about a certain matter, you should realize that the situation you are concerned about may or may not happen.
Similarly, if you are anxious about an impending event, you also know that it may or may not occur. This is a simple fact: your worry does not cause any impact or change, does it? If the situation unfolds exactly as you feared, Your anxiety will only diminish your ability to handle it.
犹太人有句谚语：“只有一种忧虑是正确的：为忧虑太多而忧虑。”这句话可谓切中要害。忧虑往往是徒劳的，它只会让人在原地打转，最终回到起点。当你对某件事感到焦虑时，应当明白，所担心的事情可能发生，也可能不会发生。
同样，如果你为即将发生的事情而焦虑，你也清楚这件事存在发生与不发生的两种可能性。这是一个简单的事实：你的忧虑不会造成任何实质性的影响或改变，不是吗？如果事情最终如同你所忧虑的那样发生了，那么焦虑只会削弱你应对该情况的能力。
