Assertions—useful self-talk (not magic affirmations)#

Picture yourself standing in front of the mirror, repeating “I am a brilliant pilot, I am a brilliant pilot.” If you already half-believe it, you might walk out feeling a little taller. But if you’re nervous before your flight test and secretly doubt yourself, that flat “I am brilliant” can ring hollow—and the gap between the words and how you actually feel can leave you feeling worse. That’s not a hunch. It’s what the research found.

So let me be straight with you up front. Assertions—positive statements you say to yourself—can genuinely help. But the version that gets sold in books and on tapes, the grand “I am [amazing thing]” identity affirmation, is the weakest and riskiest form. This page keeps what works and drops what doesn’t.

Why “I am an expert surgeon” can backfire#

The old advice was to write short identity statements—“I am an expert surgeon,” “I am a confident speaker”—and repeat them until you believed them. The trouble is that for the people who most want a confidence boost, this can do the opposite.

Wood, Perunovic and Lee (2009) had people repeat the affirmation “I am a lovable person.” For participants who already had high self-esteem, it helped a little. But for those with low self-esteem—exactly the people reaching for affirmations in the first place—repeating it left them feeling worse than a control group who said nothing. Why? When you assert something your mind flatly rejects, you don’t quietly accept it. You argue back. “I’m a brilliant pilot… no I’m not, I bounced my last three landings.” The statement summons all the counter-evidence and rubs your nose in the gap.

So here’s the shift. Aim your self-talk at what you do, not at who you are. A claim about your behaviour—“I run the pre-flight checklist top to bottom”—is something you can act on in the next five minutes. A claim about your identity—“I am an expert”—is a verdict your mind can dispute. The first builds. The second invites an argument you’ll often lose.

Process and behaviour statements#

The assertions worth keeping describe actions, habits and approaches. They’re concrete, they’re under your control, and your mind can’t easily call them liars.

When you write them, follow a few principles:

Point at a behaviour, not a trait. Use “I check the map scale when I look for a feature,” not “I am a great navigator.” Behaviours you can do today; traits are a judgement you have to earn and your mind can contest.
Be specific. Vague statements (“I do well”) give your mind nothing to grab. Specific ones (“I make clear, unhurried radio calls”) double as a tiny rehearsal of the exact thing you want to do.
Avoid negatives. Use “I keep eye contact with the audience” rather than “I never forget eye contact.” The mind has an uncanny way of skating past the “never” and hearing “I forget eye contact.” State the thing you want, not the thing you fear.
Keep them short and, if it helps, rhythmic. Short statements are easy to recall and easy to slip into a spare moment. A bit of rhythm or rhyme makes them stickier.
Frame the effort, not just the outcome. “I practise my landings until they’re smooth” wears better than “I make perfect landings,” because it affirms something you can genuinely commit to rather than a result you can’t guarantee on any given day.

You can build a whole working set this way. When I trained for my private licence, I went back through my flight reviews and turned each weakness into a behaviour statement—“I engage the park brake before I start the engine,” “I confirm flap settings on final.” Eighty of them in the end. They worked because every one named something I could actually do.

Implementation intentions: when X, I will Y#

Here’s the single most reliable upgrade to ordinary self-talk, and it barely looks like an affirmation at all. Instead of stating a goal, you pre-decide the exact moment and action: “When situation X happens, I will do Y.”

“When I sit down at my desk after lunch, I will open my flashcards before anything else.”
“When the tower clears me to taxi, I will read the clearance back slowly.”
“When I notice I’m rushing my landing checks, I will take one breath and start the list again.”

These are called implementation intentions, and they have a strong evidence base. Gollwitzer and Sheeran (2006) pooled results across more than ninety studies and found that forming a clear “when-then” plan had a medium-to-large effect on whether people actually followed through on their goals—far more than holding a goal in the abstract. The plan hands the cue (“after lunch,” “on final”) the job of triggering the action, so you don’t have to rely on remembering or feeling motivated in the moment.

This is why I’d nudge you from “I study every day” (a wish) toward “when I make my morning coffee, I review yesterday’s cards” (a plan with a trigger). Same intention, far better odds.

Frame it as a tool, not a spell#

A few things to keep straight, so you use these for what they’re actually good for:

They support action—they don’t replace it. Saying “I learn this material easily” does nothing on its own. Its job is to keep your internal dialogue from sabotaging the study you then sit down and do. If you want to lose weight, the assertion might get you to the gym; the gym does the rest.
They beat negative self-talk, which is the real point. The win here isn’t inflating yourself into a genius. It’s swapping “I always stuff up my radio calls and everyone hears it” for “I make clear radio calls; when I fumble one, I slow down and try again.” That’s straight out of cognitive behavioural practice: catch the harsh, sweeping thought and replace it with something fairer and more useful. Notice the replacement isn’t a fantasy—it’s believable, which is exactly why it sticks.
Make them believable. If a statement makes you wince because it’s so far from true, it’s the wrong statement. Dial it back to something you can say without your mind shouting “rubbish.” “I’m getting steadier with practice” will do more for you than “I am the world champion.”
They only work on you. You can’t assert someone else into liking you. “Person X likes me” hangs on something changing in person X. You can affirm your own behaviour—how you show up, how you treat people—and let that change the odds.

The takeaway: drop the grand “I am [trait]” affirmations, especially on the days you’d need them most—they can backfire. Instead, talk to yourself about what you do: specific, believable behaviour statements, and “when X, I will Y” plans for the moments that matter. Keep it grounded, keep it concrete, then go and do the thing.
