"专长是平庸者的口头禅。"

The core idea here is that people who solely focus on becoming experts might settle for mediocrity. They get so wrapped up in mastering the rules and details that they miss out on the creativity and innovation that drive real excellence. In simpler terms, if you're always playing it safe by sticking to what you know, you might never reach your full potential.

This sentiment can be traced back to various thinkers who emphasize creativity over rigid expertise. For instance, Albert Einstein once said, "Imagination is more important than knowledge." He believed that without creativity, knowledge alone wouldn't lead to groundbreaking discoveries. The quote you provided echoes this thought by suggesting that expertise can sometimes be a comfort zone for those who are content with "good enough."

Let's talk about a real-life example. Think about Steve Jobs and how he revolutionized the tech industry. Jobs didn't just aim to be an expert in technology. Sure, he knew his stuff, but he often stepped beyond the boundaries of expertise to create something entirely new. He focused on design, user experience, and the integration of technology into everyday life. The iPhone wasn't just a better phone; it was a whole new way of looking at communication and technology. Imagine if Jobs had settled for just being an "expert" in existing technology—Apple might have been just another tech company.

To apply this wisdom in your own life, don't be afraid to step outside your comfort zone. If you're an expert in something, that's great—but don't let it make you complacent. Challenge yourself to think differently. If you're a writer, try a new genre. If you're a programmer, dabble in a new language or a completely different project. The idea is to keep pushing your boundaries and not to settle for what you already know.

Here’s a relatable scenario: Imagine you're a chef. You've mastered French cuisine—you're an expert, no doubt about it. Your dishes are technically flawless, and your restaurant is doing well. But then you start to feel a bit bored, like you're just going through the motions. You could stay in your lane and continue being a French cuisine expert, or you could take a risk. Maybe you start experimenting with fusion cooking, blending French techniques with Thai flavors. At first, it feels awkward and you make a lot of mistakes. But slowly, you create something unique, something that excites both you and your customers.

By stepping beyond expertise, you open up a world of possibilities. You might stumble, but you also might discover something extraordinary that you'd never have found if you stuck to what you knew.

So, the next time you're tempted to just "stick with what you know," think about how you can push the envelope a bit. Don't let the pursuit of expertise make you mediocre. Dive into the unknown, mix things up, and see where your creativity can take you.
