This matters because

The structure is very simple. First, state a fact or a piece of data. Then, say This matters because. Finally, explain the impact on your listener or the situation. It works best when the reason is not immediately obvious. Don't use it for things that are already clear. Use it to highlight a deeper connection or a hidden benefit. It acts like a highlighter for your most important points in a conversation. It forces you to be clear about your intentions.

This is a powerhouse in professional settings. Use it during a business presentation to explain a graph. Use it in a job interview to link your skills to the company's needs. It is also great when you are trying to persuade someone to see your point of view. Even in casual life, it works when explaining a complex hobby or a specific choice. If you are teaching someone a new skill, use it often. It helps the "lesson" stick in their brain by providing context.

Avoid using this for extremely simple or obvious things. If you say, "It is raining, and this matters because you will get wet," you sound a bit condescending. It can feel too heavy for light, breezy small talk with strangers. Don't use it every two minutes in a single conversation. It loses its power if you over-rely on it. It is a tool for emphasis, not a filler word like um or like. If the connection is already clear, just state the fact.

In many English-speaking business cultures, people value directness and efficiency. Time is money, right? Listeners often want the "bottom line" immediately. This phrase became a staple of modern public speaking, especially in the style of TED Talks. It reflects a culture that prioritizes clear "takeaways" and actionable information. It shows you respect the listener's time by getting straight to the point. It is the verbal equivalent of a "Key Takeaway" box in a textbook.

You can mix it up to keep things fresh. Try The reason this is important is... for more weight. Use Why does this matter? as a rhetorical question before answering yourself. For a more casual vibe, try The big deal here is.... In very formal writing, you might see This is significant due to.... You could also say The takeaway here is... if you are summarizing a long story. Each variation changes the "flavor" but keeps the same core purpose.
