You’re probably familiar with the "fake it till you make it" vibe. People tell you to think happy thoughts, but honestly, most of that advice feels like cheap wallpaper over a cracked wall. It doesn’t stick because it feels forced. However, there’s some actual, gritty science behind the specific vocabulary we use. Specifically, words that start with a positive prefix or carry an inherently "upward" charge—think terms like "abundance," "affirm," or "amiable"—do more than just sound nice. They literally change how your brain processes stress.
It’s about neural pathways. When you constantly reach for "catastrophe" or "impossible," your amygdala—that tiny, almond-shaped part of your brain that handles fear—stays on high alert. It's exhausting. But switching your lexicon to include more words that start with a positive orientation can lower cortisol. It's not magic. It’s neurobiology.
The Linguistic Priming Hack
Language isn't just a tool for communication; it’s a filter for reality. In psychology, we call this "priming." If I show you the word "yellow" and then ask you to name a fruit, you’re way more likely to say "banana" than "apple." Your brain is already leaning in that direction.
The same thing happens with your mood. If your day is filled with words that start with a positive slant, you’re priming your brain to seek out opportunities rather than threats. For example, using the word "advantage" instead of "obstacle" doesn't just change the sentence; it changes your blood pressure.
Researchers like Dr. Andrew Newberg and Mark Robert Waldman, authors of Words Can Change Your Brain, have found that even a single word has the power to influence the expression of genes that regulate physical and emotional stress. If a single word can do that, imagine what a dedicated vocabulary shift can accomplish over a month.
Why the Letter A is a Powerhouse
It’s kinda weird when you look at the alphabet, but the letter 'A' is stacked with some of the most impactful words that start with a positive vibe. You’ve got abundance, accomplish, admire, and authentic.
Think about the word authentic. In a world that feels increasingly filtered and fake, especially with the rise of deepfakes and AI-generated everything in 2026, authenticity is the ultimate currency. When you describe someone as authentic, you aren't just saying they’re "good." You're saying they are reliable. That’s a massive distinction.
Then there’s abundance. Most of us live in a state of perceived scarcity. Not enough time. Not enough money. Not enough sleep. By consciously choosing to use the word abundance—even in small ways, like "an abundance of options"—you're training your brain to stop scanning for what's missing. You start seeing what's actually there.
Beyond "Nice": The Power of Precision
Let’s get real: "Good" is a boring word. It’s a placeholder. It’s what you say when you don’t want to think. If you want to actually influence your environment, you need precision.
Precision creates clarity.
Instead of saying a meeting was "good," try productive or enlightening. Instead of saying a friend is "nice," maybe they are altruistic or amiable. These words that start with a positive focus give your brain a specific target.
- Ameliorate: A fancy way of saying "make better." Use this when you're talking about a bad situation. It acknowledges the problem but focuses entirely on the fix.
- Aptitude: This focuses on potential. It’s a growth-mindset word.
- Affable: It sounds sophisticated, sure, but it also describes a specific type of warmth that "nice" just doesn't capture.
The Dopamine Connection
Every time you use a word that resonates with a positive outcome, your brain gets a tiny, microscopic hit of dopamine. It’s the reward chemical. Negative words, on the other hand, trigger the release of stress chemicals like cortisol and adrenaline.
Over time, if you’re a person who constantly uses "disaster," "terrible," or "unfair," you are essentially marinating your brain in stress hormones. It’s a slow-motion car crash for your mental health. By intentionally pivoting toward words that start with a positive sentiment, you’re choosing a different chemical bath. It’s basically DIY brain chemistry.
Does This Mean We Ignore the Bad Stuff?
Honestly, no. That would be toxic positivity, and that’s just as harmful as being a total cynic. If something sucks, it sucks. Pretending a layoff is an "exciting new journey" immediately after it happens is just gaslighting yourself.

The goal isn't to lie. The goal is to balance the scales.
Humans have a natural "negativity bias." Evolutionary-wise, it was more important for our ancestors to remember where the lion was than where the pretty flowers were. We are hardwired to notice the bad. Because of that, we have to work twice as hard to notice the good. Using words that start with a positive prefix is a conscious effort to counteract a million years of evolution that wants us to stay anxious and afraid.
Real-World Business Impacts
In a professional setting, your vocabulary is your brand. Leaders who use constructive, forward-leaning language tend to have higher retention rates.
Think about the word accountability. For a long time, people used it as a weapon—a synonym for "who can I blame when this goes wrong?" But in a positive corporate culture, accountability is about ownership and empowerment. It’s a word that starts with a positive trajectory when used correctly. It means "I have the power to affect the outcome."
And then there's ambition. In some circles, ambition is treated like a dirty word, like you’re "climbing over people." But true ambition is just the desire to improve. It's a catalyst. When a team uses ambitious language, they aren't just setting goals; they’re creating a shared vision of a better future.
How to Actually Use This Without Looking Like a Weirdo
You don't need to start talking like a motivational poster. That’s annoying. You don't need to use "astounding" every five minutes.
Start small.
Next time someone asks how you are, instead of the standard "fine" or "busy," try "I’m actually feeling pretty accomplished today." It changes the energy of the conversation immediately. Or, if you’re giving feedback, use words that start with a positive frame like appreciate or advancement.
- Audit your emails. Look at the last five emails you sent. How many "negative" words did you use (don't, can't, won't, problem)? Try to swap at least two of them for a positive alternative in your next draft.
- The Morning Prime. Pick one "A" word—like alert, appreciative, or active—and make it your unofficial theme for the day. You don’t have to tell anyone. Just keep it in the back of your mind.
- Correct the spiral. When you catch yourself saying "This is a nightmare," stop. Is it a nightmare? Or is it a attainable challenge that’s just currently frustrating?
The Science of "Affirmations" (That Actually Work)
Most affirmations fail because they are too far from your current reality. If you feel like a failure and you look in the mirror and say "I am a billionaire genius," your brain just laughs at you. It creates "cognitive dissonance."
Instead, use words that start with a positive direction that are actually believable.
"I am acquiring new skills."
"I am adjusting my strategy."
"I am approaching this with an open mind."
These are active, process-oriented words. Your brain can get behind them because they don't require a leap of faith; they just require a shift in perspective.
Final Thoughts on the Vocabulary Shift
The words we choose are the bricks we use to build our world. If you use cracked, heavy, dark bricks, you’re going to end up living in a cellar. If you use words that start with a positive energy, you start building something with windows.
It's not about being perfect or happy all the time. It’s about being intentional. It's about recognizing that "amiable" is a better vibe than "hostile" and that "abundance" is a more productive mindset than "lack."
Actionable Next Steps
- Identify your "Trigger Words": Pay attention to the negative words you use most often. Is it "stressed"? "Hate"? "Stupid"? Find their positive opposites and keep them in your "linguistic back pocket."
- The 3-to-1 Ratio: Try to use three words that start with a positive connotation for every one negative word you use in a conversation. This is based on the Losada Ratio (though the specific math is debated, the principle of "positive offset" is sound).
- Rename Your Folders: This sounds silly, but rename your "Bills" folder to "Accounts" or "Affairs." Rename your "To-Do" list to "Achievements." The subtle shift in how you view these tasks reduces the micro-stress associated with them.
- Read More Diverse Text: Expand your vocabulary by reading authors who use nuanced language. The more words you have available to you, the less likely you are to fall back on lazy, negative slang.
By tightening up your vocabulary and leaning into words that start with a positive charge, you aren't just changing your speech. You’re rewiring your brain for a more resilient, capable version of yourself. It’s a low-effort, high-reward habit that starts the moment you choose your next word.
