"心も体も、快適さのあまりにしばしばニキビだらけで状態が悪くなることがある。"

The quote suggests that just as our bodies can become unhealthy due to too much comfort and lack of activity, our minds can also deteriorate if we don't challenge them enough. When we get too comfortable, we might become lazy, uninspired, or even anxious and depressed. It's like when you eat too much junk food and don't exercise—your body suffers. The same goes for your brain.

Historically, this idea has been echoed by many thinkers and philosophers. For example, in the mid-1800s, a period of rapid industrialization and increasing comfort, many people started noticing that despite greater material wealth, there was a rise in mental unrest and dissatisfaction. This was a time when people began to realize that simply having more comfort and ease in life didn't necessarily lead to happiness or mental well-being.

Let's consider a real-life example. Think about the story of a successful entrepreneur who, after years of hustle and struggle, finally "makes it." They buy a big house, a fancy car, and can afford all the luxuries they once dreamed of. For a while, it feels like they've achieved their goals. But after some time, they start feeling restless and unfulfilled. Without the challenge and drive that once pushed them, their mind starts to wander into negative spaces. They may even become depressed, despite their outward success. This story isn't uncommon—many people find that once they stop striving, their mental health can deteriorate.

If you're wondering how to apply this wisdom to your own life, think about ways to challenge yourself regularly. This doesn't mean you need to be in a constant state of stress, but consider setting new goals, learning new skills, or tackling new projects. It could be as simple as picking up a new hobby, reading challenging books, or engaging in stimulating conversations. The key is to keep your mind active and engaged.

Imagine a scenario where you're working a job that's pretty easy and pays well, but it's not challenging you anymore. You might start feeling like you're in a rut. What can you do? You might take on a new project at work, something that pushes you out of your comfort zone. Or, perhaps you decide to learn a new language or take up painting. These activities force your brain to work harder, keeping it healthy and sharp.

In essence, to keep your mind in good condition, you need to embrace challenges and avoid falling into the trap of too much comfort. Just like you'd mix up your workout routine to prevent your body from getting too used to one kind of exercise, you should mix up your mental activities to keep your brain fresh. Life's not just about coasting along; it's about finding that balance between comfort and challenge. So, next time you feel a bit too comfortable, think about what new mountain you can climb, literally or metaphorically. Your mind will thank you.
