This Is the Most Important Skill to Get Success with AI Tools
It's Not About Prompt Engineering
Imagine asking an AI for a simple list of ideas and being buried under a wall of text—overwhelming, right? That’s the reality of working with large language models (LLMs) and other AI tools. They can generate massive amounts of output in seconds, but many of us struggle to use it effectively, bogged down by the urge to read every word like it’s a rare manuscript.
But here’s the truth: the key to success with AI tools isn’t about crafting the perfect prompt—it’s the ability to skim and know what’s important.
While prompt engineering might refine what AI spits out, it’s skimming that lets you navigate the flood of output, iterate fast, and tap into AI’s real power. In this article, we’ll dive into why we overthink LLM output, how skimming saves the day, and why expertise makes you better at it.
Why We Treat LLM Output Like a Book (And Why That’s Wrong)
For centuries, text was rare and costly. Scribes painstakingly copied manuscripts, and early printed books were treasures. We learned to treat words as precious, analyzing them deeply. This habit lingers today, even though information is now abundant. When faced with LLM output, we instinctively want to read every word carefully, as if it were a sacred text.
But there’s more to it. We don’t fully trust LLMs, just like we might hesitate with a junior colleague’s work. Will it hold up? Is it reliable? This trust barrier makes us overanalyze, double-checking every detail. It’s a natural response—our brains are wired to be cautious with unfamiliar tools or allies. Evolutionarily, this caution helped us survive, but with AI, it slows us down.
Psychologically, we crave certainty and fear mistakes. Overanalyzing gives us a sense of control, but it’s an illusion. With LLMs, this habit wastes the very advantage they offer: speed. The key insight is that LLM output isn’t a sacred book—it’s disposable. You can generate it again in seconds. Clinging to old habits blocks AI’s real value.
Here’s why this matters. AI tools aren’t meant to deliver perfect, final drafts. They’re designed to flood you with possibilities. Treating their output like a book keeps you stuck in the past, missing the speed and flexibility that define AI’s power.
Skimming is The Skill That Sets You Free
So, what is skimming? It’s quickly scanning LLM output to grab what’s useful—key ideas, patterns, or flaws—without reading every word. Think of it as panning for gold: you’re sifting through the stream to find the nuggets, not studying every pebble.
Why is skimming the most important skill for AI success? First, it handles the deluge. LLMs produce too much to read deeply—skimming finds the gold amid the noise. Second, it speeds up iteration. You can cycle through drafts or ideas fast, tossing what doesn’t work and refining what does. Third, it breaks the overanalysis cycle. Skimming lets you trust the AI enough to move forward, checking details only when needed.
For example, a writer skims ten AI-generated headlines, picks two that stand out, and tests them—done in minutes instead of hours. Without skimming, they’d be stuck reading each one carefully, wasting time and losing momentum.
Skimming isn’t sloppy—it’s strategic. It’s about knowing what to prioritize in a flood of options. With practice, it becomes second nature, transforming how you interact with AI tools.
AI Gives Us The Ability to Iterate Fast
Here’s where AI truly shines. In the past, creating something—writing a draft, coding a program, brainstorming ideas—took time. Humans are slow, and we’d often have only one or two options to work with. We’d polish that one idea obsessively, hoping it would succeed. But if it flopped, we were back to square one.
AI changes that. LLMs can churn out multiple options in seconds, giving you a buffet of possibilities. The advantage isn’t just speed—it’s the ability to iterate fast, trying and tweaking until you succeed. This is revolutionary. We failed before because we lacked options; now, failing to iterate squanders AI’s gift.
Skimming drives this iteration. By skimming, you evaluate and adjust outputs rapidly, learning more with each cycle. Faster iteration beats perfectionism—skimming makes it possible.
Think of it like prototyping. AI gives you ten rough sketches instead of one finished painting. Skimming lets you pick the best sketch and refine it, rather than agonizing over a single, flawed draft.
You Need Subject Matter Expertise
There’s a myth that LLMs are for novices to learn from scratch. But the truth is, experts benefit most. Why? Because experts know what “good” output looks like. They can skim with confidence, spotting quality or errors fast. It’s like a manager reviewing a junior’s work: they delegate to the AI and check results efficiently.
Without expertise, you might miss flaws or waste time on bad output, unsure what to trust. For example, an expert chef skims an AI’s recipe ideas and instantly rejects ones that won’t work, while a beginner might follow a flawed one blindly. The key insight is to think like a manager, not a student—expertise turns skimming into a superpower.
This doesn’t mean novices can’t use AI. They can, but they’ll lean harder on deep reading until they build knowledge. Experts, though, can hit the ground running, using skimming to amplify their skills.
Balance Between Skimming and Deep Reading
Skimming isn’t always the answer. There are times when deep reading is necessary. So, how do you balance the two?
Use skimming for iterative tasks—brainstorming, drafting, exploring options—where speed trumps precision. For final decisions or high-stakes output, like contracts or critical analysis, switch to deep reading. Skimming helps you explore broadly and pick what’s worth studying deeply.
For instance, skim an AI’s list of blog topics to choose one, then research it deeply for the final piece. This balance ensures you’re efficient without sacrificing quality when it matters.
The trick is knowing when to shift gears. Skimming gets you to the finish line faster, but deep reading ensures you cross it with confidence.
How to Build Your Skimming Habit
Skimming might not feel natural at first, but it’s a learnable skill. Here’s how to start:
Start Simple: Practice scanning LLM output for main ideas or red flags—ignore the fluff. Look for keywords or phrases that signal value, like “solution” or “innovative.”
Leverage the AI: Ask it to summarize or highlight key points to make skimming easier. Many tools can bold important sections or provide bullet points.
Trust First, Check Later: Skim to decide, then test in practice—only dig deeper if it fails. For example, use an AI-generated script and see if it works; if not, then investigate.
The key is to practice regularly. The more you skim, the better you’ll get at spotting what matters quickly. Start with low-stakes tasks, like brainstorming, and build from there.
Another tip: set a timer. Give yourself 30 seconds to skim a page of output. Force yourself to move fast—it trains your brain to focus on what counts.
Conclusion
Let’s recap. We treat LLM output like books due to old habits and mistrust, but it’s disposable. Skimming breaks this cycle, fuels fast iteration, and shines when paired with expertise. In an AI-driven world, skimming is the edge that keeps you ahead of the overload.
So, next time you use an AI tool, skim first—see how much faster you move. Don’t get bogged down in the flood of words. Grab what’s useful, iterate, and refine. Master skimming, and you’ll master AI.
This isn’t just a skill—it’s a mindset shift. Embrace it, and you’ll turn AI tools from overwhelming to empowering. Start today.
