"今天的科学家深思而不清晰。一个人必须头脑清醒才能清晰地思考，但一个人可以深思却非常疯狂。"

Simplified Meaning:

Sometimes, people who study science get so caught up in thinking about very complicated ideas that they forget to think in simple, straightforward ways. To understand things clearly, you have to be mentally healthy and balanced. However, it's possible to delve into very deep and complex thoughts even if your mind is not stable. Imagine a time when you were really stressed about something, and you kept overthinking it. You might have thought about it in so many complicated ways, but you couldn't see the situation clearly. For example, if you were nervous about a big test, you might imagine all sorts of complicated scenarios about failing, even though you studied hard and probably knew the material well. To apply this to your life, try to take a step back when you feel overwhelmed by your thoughts. Break things down into simpler parts, and make sure your thinking is grounded and realistic. It helps to stay calm and take care of your mental health, so you can understand situations more clearly and avoid unnecessary worry.
