By the numbers

What research says about belief in yourself.

Belief & doing

114studies (over 21,000 people) were combined in a review that linked belief in your own ability with better performance at work
4main sources of self-belief: doing it yourself, seeing others do it, encouragement, and how you read your body’s signals
200people took part in a larger test of “power poses”: they felt a bit more powerful, but their hormones and risk-taking did not change

Across life

331groups of people (over 160,000 in total, ages 4 to 94) were followed in a review of how self-esteem changes over life
60–70is roughly the age when self-esteem tends to be highest. Many people feel surer of themselves later in life than when young
6th gradeis when a gap appears in how girls and boys rate their own performance, even when they did equally well

What is confidence?

Trusting that you can handle things, even when you are nervous.

Confidence is a quiet trust that you can try something, cope with how it goes, and learn along the way. It is not the absence of nerves. Plenty of confident people feel butterflies; they just don’t let the butterflies decide for them.

Psychologists often talk about self-efficacy: your belief that you can do a particular thing. That belief shapes whether you try, how hard you try, and how long you keep going when it gets tough.

🧗 ConfidenceTrust in what you can do. It can be high in one area and low in another.
Read more

Confidence is usually about doing: cooking, driving, speaking up, playing a sport, meeting new people. You might feel sure of yourself at work and shaky on a dance floor. That is completely normal.

Because it is tied to activities, confidence can grow with practice. Each time you try something and get through it, you collect a little more proof that you can.

💛 Self-esteemHow you value yourself as a person, whatever you can or can’t do.
Read more

Self-esteem is the overall opinion you hold of yourself. The NHS notes that low self-esteem and low confidence often go together, and that both can grow from messages we picked up from parents, teachers, friends and the media.

You can have decent self-esteem and still feel unsure about a new skill. You can also be very skilled and still feel you are not “enough”. The Self-esteem guides in this app go deeper on that second part.

🦚 ArroganceActing as if you are better than others. Often a cover, not real confidence.
Read more

Healthy confidence leaves room for other people. You can say “I’m good at this” and “I could be wrong” in the same breath.

Arrogance tends to need to win, can’t admit mistakes, and puts others down. Sometimes loud certainty is protecting a fragile sense of worth underneath.

Confidence does not have to be loud. Some of the most confident people you know are calm, curious and kind.
Feeling unconfident is not a flaw in your character. It usually means you are stretching into something new, or that life has knocked you a bit. Both can change.

Where confidence comes from

Four sources you can draw on. Tap each one.

Psychologist Albert Bandura described four main sources of self-belief. The strongest is doing the thing yourself, but all four help, and you can use them on purpose.

✅ Doing it yourselfGetting through something, even imperfectly, is the strongest builder of belief.
Read more

Bandura called this mastery experience. In his early studies, people who did a feared task step by step gained more confidence than people who only watched someone else do it.

The key is steps that are small enough to manage. A win you can actually reach beats a giant leap you keep putting off.

Write down each small thing you get through. Your memory tends to keep the mistakes and drop the wins.
👀 Seeing others do itWatching someone like you succeed whispers “maybe I can too”.
Read more

Bandura called this vicarious experience. Seeing people manage something, especially people who seem similar to you, can raise your belief that it is possible.

This is one reason role models, mentors and peer groups matter. Look for people a few steps ahead of you, not only the superstars.

📣 EncouragementSomeone you trust saying “you can do this” helps, especially when it is honest.
Read more

Bandura called this verbal persuasion. Encouragement from others can nudge you to try, though on its own it is weaker than real experience.

The words you say to yourself count too. “This is hard and I’m learning” is more useful than “I’m hopeless at this”. The Self-compassion & your inner critic guide has more on this.

💓 How you read your bodyA racing heart can be read as “I can’t” or as “I’m getting ready”.
Read more

Bandura noted that people judge their ability partly from body signals like a fast heartbeat, sweaty hands or a shaky voice. If you read them as signs of failure, belief drops.

Those same signals are your body preparing to act. Calming your breathing, and reminding yourself that nerves are normal, can change the story you tell about them.

Myths vs facts

Common ideas about confidence that don’t hold up.

🧬 Myth: You are born with it or you’re notFact: Confidence grows with experience at any age.
Read more

Temperament plays a part, but self-belief is built from experience: doing, watching, encouragement and how we read our bodies. Those are things you can add to.

Self-esteem also tends to rise through young adulthood and keep growing into later life for many people. You are not stuck where you started.

😬 Myth: Confident people don’t feel scaredFact: They feel nervous too. They act anyway.
Read more

Confidence is not the same as calm. Most people feel nerves before something that matters. The difference is often that confident people have learned, from experience, that the nerves pass and they can cope.

🦸 Myth: A “power pose” rewires youFact: It may help you feel a little bolder, but the bigger claims didn’t hold up.
Read more

A larger study of 200 people found that standing in expansive poses made people say they felt a bit more powerful. But it did not change their hormone levels or how much risk they took.

So standing tall before a hard moment is fine if it helps you feel steadier. Just don’t expect it to do the work of practice and preparation.

📢 Myth: Loud means confidentFact: Quiet people can be deeply confident.
Read more

Confidence shows up in many ways: steady eye contact, a calm “no”, asking a question in a meeting, trying something new. Volume is not the measure.

The Quiet confidence for introverts guide explores confidence that doesn’t need a spotlight.
⏳ Myth: You have to feel confident before you actFact: Usually the action comes first and the feeling follows.
Read more

Waiting to feel ready can mean waiting forever. Belief tends to grow after you have done something, not before.

Small, manageable steps let you act while still nervous, and collect proof as you go.

⚖️ Myth: Confidence gaps are all in your headFact: Upbringing, culture and how people treat us shape it too.
Read more

In large experiments, women rated their own performance lower than men who had done just as well, even when they knew their exact scores. The gap appeared by sixth grade.

Messages from family, school, media and society all feed into how we see ourselves. Low confidence is not a personal failing. It often has roots outside you.

The avoidance trap

Why dodging hard things makes confidence shrink.

When something feels scary, avoiding it brings quick relief. But each time we avoid, we miss the chance to learn that we could have coped. Next time, the task feels even bigger.

How the cycle often goes

  1. A challenge comes up: a call, a class, a conversation.
  2. Worry says “you’ll mess it up”.
  3. You avoid it, and feel relieved for a while.
  4. You miss the proof that you could have managed.
  5. Next time, it feels harder, and confidence drops a little more.

The way out is not a giant leap. It is a small step toward the thing, done while still a bit nervous. Bandura found that doing feared things in manageable steps built more belief than just watching or thinking about them.

Quiet signs of avoidance

  • Always letting someone else make the call or speak up
  • Getting “too busy” whenever a certain task comes up
  • Over-preparing so long that you never start
  • Saying no to things you actually want to do
  • Turning down chances because you might not be perfect
The Fear of failure guide has a step-by-step fear ladder that pairs well with this section.

Building confidence, step by step

A simple, repeatable way to grow self-belief.

A five-step plan

  1. Pick one area where you want more confidence. Just one.
  2. Choose a step small enough that you could do it this week, even if nervous.
  3. Do it. Imperfect counts.
  4. Write down what actually happened, not just what you feared.
  5. Pick the next step, a little bigger. Repeat.
📒 Keep an evidence logCollect proof of what you can do, because your memory won’t.
Read more

The NHS suggests writing a list of at least five positive things about yourself, including kind things others have said, and adding to it. Reading it on low days balances the harsh voice.

Include small wins: “made the phone call”, “asked a question in class”, “tried the new recipe”. Small wins add up.

🎯 Set yourself challengesNew things you choose on purpose stretch your sense of what you can do.
Read more

The NHS suggests setting yourself challenges you can achieve, like joining a class or taking up a new hobby, to build belief through doing.

Choose things that matter to you, not things you think you “should” do. Meaning keeps you going when it gets awkward.

🧑‍🤝‍🧑 Borrow from role modelsWatch how people you admire handle the thing you find hard.
Read more

Seeing others succeed raises belief, especially when they are like you.

The NHS suggests copying the assertive behaviour of people you admire, while staying true to yourself. Notice the words they use, how they pause, how they recover from a slip.

🗣️ Talk to yourself like a coachFirm, warm and practical beats harsh.
Read more

Being as gentle with yourself as you would be with a friend helps self-esteem, according to the NHS.

Research on self-compassion found that people who were kind to themselves after a failure were more motivated to improve, not less.

Try: “That was hard. I did it anyway. Next time I’ll try one thing differently.”
🤗 Spend time with people who lift youWho you are around shapes how you see yourself.
Read more

The NHS suggests spending more time with people who are supportive and less with people who tend to put you down.

Progress is rarely a straight line. A wobbly week does not wipe out what you have built.

Your body, breath and voice

Small physical habits that help you feel steadier.

Your body sends signals that your mind reads as “I can” or “I can’t”. You can’t switch nerves off, but you can steady them and change the story you tell about them.

Things that can help in the moment

  • Feel your feet on the floor before you start
  • Pause before answering. A short silence feels longer to you than to others
  • Slow your out-breath: breathe in for four, out for six, a few times
  • Speak a little slower than feels natural
  • Stand or sit in a way that feels open and comfortable to you

Expansive postures may help some people feel a bit bolder, but research did not find that they change hormones or behaviour. Think of posture as a small comfort, not a magic trick.

People also tend to overestimate how much others notice their nerves or slips. In a well-known study, people thought about twice as many others had noticed an embarrassing T-shirt as actually had.

The Breathing basics guide and Public speaking & presentations guide have more ways to calm your body before a big moment.

Healthy confidence vs overconfidence

Sure enough to try, humble enough to learn.

The goal is not to feel sure about everything. Healthy confidence is realistic. It sits alongside curiosity, asking for help and admitting when you got something wrong.

🌳 Healthy confidenceWilling to try, open to feedback, okay with not knowing.
Read more
  • Asks questions without feeling small
  • Can hear “no” without collapsing
  • Celebrates other people’s wins too
  • Says “I don’t know yet”
  • Tries things where success isn’t guaranteed
🎈 OverconfidenceSkips preparation, brushes off feedback, can’t admit mistakes.
Read more

Overconfidence can look impressive at first, but it often leads to poor planning and strained relationships. Under it may be fear of looking weak.

If people often tell you that you don’t listen, it may be worth slowing down and getting curious.

🐚 UnderconfidencePlays small, avoids chances, discounts real skills.
Read more

Underconfidence can mean selling yourself short. Research found many people, especially women, describe their own abilities less favourably than their performance deserves.

The Imposter syndrome guide helps if you feel like a fraud despite clear evidence that you are capable.

Humility and confidence are partners, not opposites. Being able to say “I was wrong” is a sign of strength.

How to support someone’s confidence

Ways to help a friend, partner or family member believe in themselves.

Encouragement from people we trust is one of the four sources of self-belief. It works best when it is honest and paired with real chances to try.

Things that tend to help

  • Ask what they would like help with, rather than taking over
  • Celebrate effort and small steps, not only big results
  • Name specific things they did well
  • Offer to practise with them, like a role-play before a hard call
  • Remind them of times they coped before
  • Share your own wobbles and how you got through

Things that can backfire

  • Doing it for them every time
  • Over-the-top praise that doesn’t feel true
  • Saying “just be confident!”
  • Teasing about nerves or mistakes
Communities help too: clubs, classes, faith groups, sports teams and volunteering all give people safe places to try things and see others like them succeed.

When and where to get help

When low confidence is weighing heavily, support is available.

Most people can grow confidence with practice and support. But if low confidence comes with constant self-criticism, avoiding much of life, or feeling low most days, talking with someone can help.

It may be time to reach out if…

  • Fear of judgment stops you from going to work, school or seeing people
  • Low confidence has lasted a long time and isn’t shifting
  • You feel worthless or hopeless
  • You often feel low, anxious or on edge
  • You rely on alcohol or other substances to feel confident

The NHS notes that talking therapies such as counselling or cognitive behavioural therapy (CBT) can help with low self-esteem and confidence. A primary care provider can be a good first step. Please talk with your clinical provider about what is right for you.
