Why your presentation has too much information (and what to do about it)

Here's what happens in most presentations: The speaker knows their topic inside and out. They've done the research, gathered the data, understand all the nuances. Naturally, they want to share all of it.

But thirty slides later, the audience is nodding politely while feeling completely lost. Not because the content was bad—because there was too much of it, with no clear thread tying it together. The problem isn't that you don't know enough. It's that you haven't decided what actually matters.

Why experts struggle with this

When you're an expert, your instinct is to be thorough. You want to cover all the bases, show your depth of knowledge, leave nothing out. That feels responsible. It feels like good presenting.

But what feels thorough to you often translates to overwhelming for your audience. They won't sift through everything you said and identify the key takeaway on their own. They won't connect the dots between your seven main points and figure out which one actually matters. They'll just disconnect — because deciding what's relevant is hard work, and that's supposed to be your job, not theirs.

What the best presentations have in common

Think about a presentation that actually stuck with you. What made it memorable? Probably not the number of slides or the sheer volume of information. More likely, it was crystal clear what the speaker wanted you to understand — one idea, explored deeply, with everything else supporting that central point.

TED Talks work this way. "Ideas worth spreading" — one talk, one idea. Not five ideas crammed into eighteen minutes. The constraint is what makes them powerful.

The question you're probably not asking

Most people preparing a presentation ask themselves: What do I want to cover? What does my audience need to know? How do I organize all this information?

But the most important question is this: If my audience remembers only one thing, what should it be?

That's your core message. Until you can answer it in one sentence, you're not ready to build slides.

How to find it

Here are the questions I ask clients when we're working to clarify their message:

What do you want your audience to do or think differently after this?

"Understand our strategy" is too vague. "Feel confident investing in this project" is better—but you can push further. Why should they be confident? What specifically changes for them?

Why does this matter to them?

Not to you. To them. What value are you actually offering? How will their work, their business, their decisions be different after hearing this?

What are you choosing NOT to say?

This might be the hardest question. What context are you leaving out? What details are you skipping? What tangents are you resisting? If you can't answer this clearly, you haven't made real choices yet.

What changes when you get clear

Once you know your core message, everything else becomes easier. You know which slides to keep and which to cut—even when the content is interesting. You know how to structure your presentation so it builds toward that one clear point instead of wandering. You know what deserves detail and what can be mentioned briefly or not at all.

And your audience can actually follow you, because you're not asking them to do the filtering work.

Need help finding your core message?  Sometimes the most valuable thing is having someone ask you the hard questions: the ones that force you to get specific. Let's talk.
