Often, students would begin with strong ideas, but have trouble focusing their thoughts when it came time to translating those ideas into words  — resulting in essays with loose, distracted, and ultimately, confusing arguments. It’s not that their ideas weren’t valuable. There were just too many of them to digest at once.

Luckily, there is a (memorable) strategy that can help any level of writer greatly improve their work. I call it the one-idea rule: Every component of a successful piece of writing should express only one idea.

You may be familiar with some of the variations of this rule, like the Pyramid Principle or Purdue’s rules of thumb for paragraphs. After all, every great essay, article, or written work is grounded by a foundational idea — one that equally inspires the author and their audience.

In persuasive writing, which we will focus on here, your one idea is often the argument or belief you are presenting to the reader. Once you identify what that argument is, the “one-idea rule” can help you develop, revise, and connect the various components of your writing in a clear and convincing way.

For instance, let’s say you’re writing an essay. There are three components you’ll be working with throughout your piece: the title, the paragraphs, and the sentences. Each of these parts should be dedicated to just one idea. The ideas are not identical, of course, but they’re all related. If done correctly, the smaller ideas (in sentences) all build (in paragraphs) to support the main point (suggested in the title).

Why should you follow this rule?

There are many advantages to using the one-idea rule, but I’ll point out three that are particularly important:

You will sharpen your focus. Many written pieces fail to be persuasive because they include too many ideas rather than too few. Having a clear end goal will keep you disciplined.

You will make more discoveries (and have more fun). Focus gives you freedom. When you have one specific idea you’re trying to portray, you can then experiment more broadly throughout your piece or even take a little detour without losing sight of your main point. You can dig more deeply into certain details, as long as they are related to the title, or your main idea.

You will become more confident. Knowing that you’re following a rule that describes all good writing gives you a chance to assess the quality of your own work, as well as the work of others — including your peers, your colleagues, and even well-known authors. Great writing is a skill, and once you understand how to structure papers in a compelling way, you’ll gain the confidence to decide what makes a piece truly interesting and persuasive.

How to Get Started

This rule may sound simple, but it takes practice to master.

So, what should you do the next time you begin an assignment, and you face the terrifying abyss of a blank page and a blinking cursor? How can you identify what your big “idea” is?

These three steps can help sharpen your focus.

[Here’s the first.]

1) Find an angle.

Maybe you’re writing on a topic that was assigned to you by an editor or a professor. Maybe you’re brainstorming a piece to pitch to a media outlet. Or maybe there is a subject you want to tackle but your focus feels too broad. Whatever the case, you have to come up with an angle — a clear and refreshing perspective on the topic at hand that presents a specific, unique, and well-supported argument or “idea.”

If you don’t know what argument you want to make, then you’re in trouble. To figure it out, ask yourself questions about the topic that tease out details related to it:

• What do I know about this topic?
• What do I not know about this topic but want to learn?
• What inspires me about this topic?
• Would others also find these issues interesting?

As you answer these questions, useful insights, questions, and unknowns will arise. For instance, perhaps you are interested in writing about “Mental Health on College Campuses.” Answering the questions listed above, may lead you down a path of discovery:

• What do I know about this topic?
  • “I’ve seen on the news that many college students are depressed or dropping out.”
• What do I not know about this topic but want to learn?
  • “I don’t know many details about mental health issues on college campuses specific to this pandemic.”
• What inspires me about this topic?
  • “It would be great to discover new solutions to the problem or find the best existing solutions, and explain them clearly to readers.”
• Would others also find these issues interesting?
  • Students themselves, and institutions trying to support them, may be interested.

From here, you might start out with the goal of writing about “solutions to mental health problems faced by college students.” That’s a good start, but it’s still too vague, and may be challenging for you (someone just beginning to study the issue) to tackle effectively.

The good news is that you can narrow down your idea. Coming up with a headline is a great way to do this. For example, you might title your paper, “3 Ways Colleges Can Address Mental Health Issues Among Students.” Notice how your focus immediately narrows. This will help you stay on track and investigate a clearer solution to the problem you have identified.
