"如果你开始思考你的身体或道德状况，你通常会发现自己生病了"

The essence of this quote lies in the idea of overthinking our physical or moral state. It's that notion that when you start scrutinizing yourself too intently, you often end up finding flaws or problems that might not have been there if you weren't so hyper-focused. In other words, the more you nitpick at yourself, the more likely you are to believe something's wrong.

Historically, this perspective has roots in both psychological and philosophical thought. Early philosophy often warned against over-analysis of oneself. Figures like Socrates and later existentialists like Sartre discussed the perils of being overly introspective, suggesting that it can lead to unnecessary angst and self-doubt. This particular quote could've been echoed anytime someone noticed the human tendency to create problems out of thin air by merely focusing too much on the negatives.

Let's imagine a real-life example. Think of a hypochondriac. Jane, for instance, often finds herself spiraling into anxiety every time she feels a minor ache or pain. She starts Googling symptoms, and before she knows it, a simple headache has transformed into a self-diagnosed brain tumor. This excessive focus on her physical condition makes her feel perpetually unwell, though she might be perfectly healthy. By constantly fixating on her health, she's tricked herself into feeling sick.

So, how do you apply this wisdom? For starters, practice mindfulness. It sounds cliché, but staying present and focusing on the now really helps. Instead of diving deep into every little detail of what's wrong, shift your attention to what’s right. When you catch yourself spiraling, pause, take a deep breath, and redirect your thoughts. It’s about finding a balance between being aware and being obsessed.

Here's a relatable scenario. Imagine you're preparing for a big presentation at work. You start picking apart your public speaking skills. You think, "Am I speaking clearly? Is my accent too thick? Do I sound nervous?" By the time you’re up there, you’ve convinced yourself you’re going to bomb. But if you’d focused on the preparation and what you do well, you’d likely feel way more confident.

I remember a time when I was constantly worried about my moral integrity. I’d question every little action—did I offend someone with that joke? Was I too harsh in my feedback? It reached a point where I was paralyzed by my own second-guessing. Then a friend told me, "Just do your best. Overthinking won’t change what’s already done." That kind of shook me. I realized I was making myself "sick" with worry over things that I couldn’t change and, quite frankly, probably weren’t as bad as I imagined.

So, take a step back. Trust in your basic goodness and health. Next time you catch yourself micromanaging your every move or feeling, tell yourself it’s okay to let go a bit. You’ll find that when you stop searching for flaws, you feel a lot more whole.
