The Domino Effect of Expertise

For much of my 20s, I worked for a company with a bold approach.

We trained people, usually recent graduates, how to teach English as a foreign language (TEFL). We equipped them with the skills and confidence to do it in classrooms around the world.

While most of the industry stuck to the traditional four-week, classroom-based qualification, our founder took a different path.

She made the training more flexible, more accessible, and more affordable – introducing shorter and online formats that opened the door to far more people to take their expertise abroad.

As product lead, I was responsible for developing our core offer. That meant working closely with experienced TEFL trainers – people who’d spent years honing their craft in classrooms across the globe.

My job was to distil their knowledge into practical, engaging course products that gave our learners the confidence to start teaching from day one.

As the role evolved, I spent more time overseas, visiting schools and observing newly qualified teachers in action. And what I saw has stayed with me.

These teachers were thriving.

Many were having the kind of life-changing experiences they’d only dreamed of – exploring new places, immersing themselves in new cultures, and growing in ways you can’t script.

But the impact didn’t stop there.

They were teaching children, often in communities where English opened real doors. These kids weren’t just learning grammar or vocabulary. They were gaining a tool that could change the course of their lives: better jobs, further education, a bigger world.

That’s when it clicked.

Expertise, when it’s packaged well, doesn’t sit still.

It moves.
It travels.
It triggers change.

We took insight from those who had been there and done it, and turned it into something that could scale. Something that moved people, quite literally, and kept moving through the lives they touched.

It was a domino effect. One action. Many outcomes.

And it’s this kind of quiet, cumulative impact that still drives the work we do today.

So here’s a challenge for you:

👉 What’s the domino effect of your work?

Take a moment. Acknowledge the work you’ve already done and what you’ve already set in motion.

Then ask: How could you amplify it?

How can you make that impact go further, last longer, reach more people?
