How Self-Talk Builds Confidence

By Jessica Lewis MA, AMFT, CMPC, Associate Therapist

What if one of the most powerful tools for building confidence is something you already have with you every day?

Your voice.

Not the voice of your coach, your parents, your teammates, or the people around you—but the voice inside your own head.

Through my work in mental performance and sport psychology, I have had the opportunity to work with elite athletes across a wide range of sports, backgrounds, and stages of development. One of the most consistent things I have learned is that confidence isn't something you either have or don't have. It is a skill that can be practiced and strengthened.

And one of the simplest places to start is with the way we talk to ourselves.

Your thoughts shape your response

Imagine an athlete makes a mistake during a game. One athlete thinks, “I always do this. I'm terrible under pressure. I'm going to mess up again.” Another thinks, “That wasn't my best play. Reset. I know what I'm capable of.” The mistake is the same. But the internal response is completely different.

The way we interpret an experience can influence how we feel, and those emotions can affect how we behave and the decisions we make. In sport, an athlete who believes “I can handle this” may be more likely to stay engaged, recover from mistakes, and make confident decisions. An athlete who repeatedly tells themselves “I can't do this” may become more hesitant, overwhelmed, or afraid to take risks.

Confidence doesn't mean never feeling nervous, doubtful, or afraid. It means learning that you can experience those emotions without allowing them to dictate what you do next.

Self-talk isn’t just for athletes

You don't have to be an athlete to experience self-doubt.  Maybe you walk into a job interview thinking, “They're probably going to choose someone more qualified.” Maybe you're afraid to speak up in a meeting because you're thinking, “What if I sound stupid?” Maybe you're entering a new relationship and find yourself thinking, “I'm not interesting enough for them.” Or maybe you make a mistake and immediately tell yourself, “I should have known better. I always mess things up.” These thoughts can feel automatic, but they don't have to be the final word.

The goal isn't to force yourself to think positively all the time or pretend that difficult emotions don't exist. The goal is to notice your inner dialogue and learn to respond to yourself in a way that is more supportive, realistic, and useful.

Instead of: “I'm not good enough.” Try: “I don't have to be perfect to be capable.”

Instead of: “I'm going to mess this up.” Try: “I can handle whatever happens.”

Practical tools

One simple technique I use with athletes is creating a physical cue to interrupt negative self-talk.

Try wearing a rubber band or bracelet around your wrist. When you catch yourself engaging in harsh or self-defeating thinking, use that physical cue as a reminder to pause, take a breath, and reset.

Then ask yourself:

“What would I say to someone I love if they were thinking this about themselves?”

Now say that to yourself.

You can also create a short phrase that becomes your personal reset:

“Breathe. Reset. Trust yourself.”

“I can do hard things.”

“I don't need to be perfect. I need to be present.”

The most effective self-talk is believable. If you're anxious, you don't need to tell yourself, “I'm completely calm.” Try, “I'm nervous because this matters to me.”

That shift is powerful because you're not trying to eliminate the emotion. You're reminding yourself that the emotion doesn't have to control your behavior.

The relationship you have with yourself matters

We spend so much of our lives thinking about how we relate to other people, yet the relationship we have with ourselves is one of the most important relationships we'll ever have.

When we constantly criticize ourselves, mistakes can begin to feel like evidence that we're not good enough. But when we learn to respond to ourselves with compassion and encouragement, mistakes can become opportunities to learn rather than reasons to validate our negative core beliefs.

That doesn't mean letting ourselves off the hook. It means holding ourselves accountable without believing we are unworthy because we are imperfect.

Over time, practicing healthier self-talk can create something deeper than confidence. It can create self-trust, self-acceptance, and self-love.

And when you trust yourself, you may be more willing to take risks, pursue meaningful opportunities, set boundaries, communicate honestly, and show up authentically in your relationships.

Confidence is a practice

Whether you're stepping onto a field, walking into an interview, starting a new relationship, giving a presentation, or simply navigating a difficult day, the voice inside your head is coming with you.

So the next time you catch yourself saying, “I can't do this,” pause.

Take a breath.

Notice the thought.

And ask yourself:

“If I believed in myself right now, what would I say?”

Then say it.

Because confidence isn't something you have to wait to feel.

It is something you practice—one thought, one choice, and one moment at a time.
