Your confidence can vanish the second something goes wrong. One rough patch, one piece of critical feedback, and the whole thing wobbles. Most advice will tell you to believe in yourself harder. I want to tell you why that doesn't work, and what does.
I'm Jule Kim, an executive coach, and confidence is most of what my clients come to me for. The version of confidence you've probably been sold, the one that's supposed to feel like nothing can touch you, was never going to hold up. It's resting on the wrong thing.
Let me show you what I mean, using my parents.
A year ago, right before I flew to London to run a workshop, I FaceTimed them to say hi. My dad's first words: "Wow, you look really tired. Make sure you wear lots of makeup in London." Then my mom leaned in with, "And do something with your hair, it looks fugly." Criticism is our love language, what can I say. I laughed, because it was genuinely super funny.
That's what stopped me. Ten years ago, that exact phone call would have wrecked my whole week. The comments hadn't changed. I had. I couldn't tell you how, so I went looking, and this piece is what I found.
Confidence definition: what the word actually means
I asked around 50 people to describe confidence. Almost all of them said some version of "feeling good about yourself." That's what I used to think too. I pictured real confidence as feeling so solid that nothing, not a hard day, not even my parents, could rattle me. The trouble with that picture is that nobody could tell me how to get there. It was a destination with no road.
So I looked up the word, because I'm a big ol' nerd. Confidence comes from the Latin for complete trust. That one detail rearranged everything.
Here's a definition of confidence that has held up for me ever since. Confidence is complete trust in yourself, built by showing up for yourself again and again, especially when it's hard. The whole thing turns on that word trust, which is the part most confidence advice breezes right past.
Confidence definition: what the word actually means
I asked around 50 people how they’d describe confidence. Most of them said some version of “feeling good about yourself.” I used to think the same thing. I believed real confidence meant feeling so solid that nothing could touch you, that even when life got hard, even when you ran into people who criticized you, you’d stay unbothered.
But the million dollar question is how you actually get there. Nobody could tell me that.
So I looked it up, because I’m a big ol’ nerd. The word confidence comes from the Latin root meaning complete trust. That one detail changed how I saw the whole thing.
Here’s a simple definition of confidence that has held up for me ever since: confidence is complete trust in yourself, built by showing up for yourself again and again, especially when things are hard. That word “trust” is the key that most confidence advice skips right over.
Why the confidence you were sold keeps collapsing
TThink about someone you genuinely trust. That trust didn't show up on day one. You trust them because they kept showing up for you, and if they showed up when things were hard, you trust them even more. Trust is earned in reps.
Your relationship with yourself runs the same way. Self-confidence grows every time you show up for yourself, and it grows fastest in the hard moments, because those are the reps that count double.
This is also why "feeling good about yourself" falls apart the second life gets bumpy. A feeling is weather. It shifts with the day, so anything built on it shifts too. One bad week, one rough piece of feedback, and it's gone. Trust is sturdier, because it runs on evidence instead of mood. That is the difference between a good day and a confident life.
How to be confident: treat it as a habit, not a feeling
Once I saw confidence as self-trust, it stopped being a mystery. Confidence isn't only something you feel. It's something you do, over and over, until it holds. It's a habit.
If you've been searching for how to be confident and nothing sticks, this is why. You were waiting for a feeling to show up, when the thing that lasts is a practice you build. So here's a question worth keeping somewhere you'll see it. If confidence is a habit, what are you practicing every day? In almost any moment, you're adding a rep to self-trust or a rep to self-doubt.
When I went back through my own client work, three habits kept separating the people who felt steady from the people who felt shaky. What you think, what you say, and what you do.
How to build confidence through three daily habits
1. What you think
I had a client who never said no at work because she didn't want to look dumb. She was spinning a thousand plates and running on empty, all because of one story on a loop: I have to do everything, perfectly, or they'll realize I don't belong. That's the single most common thought I hear from the women I coach.
Here's the part that changes things. You don't have to believe everything you think. You really don't. A thought is like that one friend who tells the same story every time you see them. You don't argue. You nod, you say hi, you keep walking. Do that with the thought. Notice it, tell it "yep, I hear you, brain," and choose a different one to follow, because you do get to choose what comes next.
How to practice it:
- Name the story. Write down the exact sentence your brain reaches for when you feel exposed. Naming it drains a surprising amount of its power.
- Stop arguing with it. You don't have to prove it wrong, you just have to stop treating it as true.
- Pick your replacement on purpose. Mine is "we're all learning as we go, and that's totally okay." Choose one you can actually lean on, and use it on repeat.
2. What you say
Years ago I met a woman with an unusual amount of free time. Turned out she didn't work, because she had passive income from real estate. When I asked how, she said she saved for 11 years, then watched the market every single day for a year before she bought. Then she shrugged and said, "It really wasn't anything special, I just got lucky." What? Are you insane? Eleven years of saving is not luck.
We do this constantly. We shrink our own wins, and it shows up most in how we take a compliment. Instead of receiving it like the gift it is, we smack it down like we're allergic. Every time you do that, you teach yourself that your work doesn't count and that you won't be the one to back it. That's a withdrawal from self-trust.
How to practice it:
- Trade "I got lucky" for "I did this." Small swap, and your brain keeps score.
- When someone compliments you, for the love of God, just say thank you. No qualifier, no correction, no list of why they're wrong.
- Keep a line ready for when you catch yourself shrinking. Mine is "repeated luck is never luck."
3. What you do
The third habit lives in your body. Picture how you sit when you feel less than, when you'd rather not be seen. Shoulders round, arms and legs cross, eyes drop. You make yourself smaller. I was a master at this. I was the person you wanted next to you on a plane, because I would not fight you for the armrest, like, ever.
What I didn't get back then is that shrinking sends your own body a message: you don't belong here. Posture is a conversation, and your body is listening to your half of it. So give it something else to hear. Head up, spine long, shoulders down and back, chest open. Take the armrest, and while you're at it, take up all the room that's yours. You can borrow the posture of confidence before you feel it, and the feeling tends to follow the body.
How to practice it:
- Run a ten second reset before anything that scares you a little. Head up, spine long, shoulders back, chest open.
- Claim your space on purpose in the rooms where you usually shrink. Feet planted, arms uncrossed.
- Let the body lead when the feeling hasn't arrived. Standing like you're confident is often what calls the confidence in.
The other half: stop tearing yourself down
Building those three habits is only half the job. The other half is quieting the voice that tears you down, and honestly this half might matter more. You can practice all day, but if your inner monologue runs on what I call 50 shades of should (I should be further along, I should be different, I should be perfect), it cancels the work out. For me that voice was louder and crueler than anything my parents ever said. It's like driving with one foot on the gas and one on the brake. All that effort, and you barely move.
That London trip actually happened, by the way. A week later I'm back on FaceTime with my parents, and my mom studies me on the iPad and says, "Your hair looks really good today. Is that a wig?" My parents are all kinds of special, I could not make them up. The difference now is that it doesn't land, because I treat myself with kindness first. That's the real turning point. People will never stop judging you, but their words stop finding a home inside you.
I also figured out that the self-attack was a decoy. It kept me busy hating my hair and my voice so I never had to sit with the bigger, scarier question of what I actually wanted to build.
How to get self confidence when you don't know where to start
If you keep waiting to feel ready, here's the reframe that got me moving. Everything you know how to do, you once had no idea how to do. Reading, landing a job, holding a hard conversation, all of it learned, usually while it was still hard. That's a track record, and it's yours. The people out there doing the thing you want aren't smarter or more gifted than you. They just started before they felt qualified.
So how to get self confidence in practice is smaller than it sounds. Pick one thing you've been avoiding and take a single step toward it. Confidence was never about a guaranteed outcome. It's choosing to try before you can see how it ends, trusting you'll figure it out on the way. That's really how to be confident in a way that lasts, one rep at a time, and it's what makes confidence stick.
Figuring out what your one thing is can be its own wall. That's the whole subject of an episode I made called The First Step to Confidence, where I get into a belief my dad handed me about my own voice, how it cost me years of podcast invitations, and the small, slightly terrifying move that finally broke it. If you want a concrete place to start, start there.
When you want a hand with this
Reading about self-trust and doing it in the middle of a brutal week are two different things, and I won't pretend the second one is easy on your own. This is the work I do with clients, helping women build confidence that holds when things get shaky, not just when everything's going well. If something here landed and you want support putting it into practice, you can reach out to set up a consult. No pressure, nothing to prepare, just a conversation about where you are and where you want to go.
Whatever you do next, remember this. The world already has plenty of people who won't understand you or won't back you. Don't add yourself to that list. Be first in line to have your own back, pick your one thing, and start. I believe in you.
Frequently asked questions about confidence
What is the definition of confidence?
Confidence comes from the Latin root meaning complete trust. A working definition of confidence is complete trust in yourself, built by showing up for yourself again and again, especially when things are hard. So confidence is less a feeling you wait for and more a habit you practice.
How do you build confidence?
You build confidence by strengthening self-trust, and three daily habits do most of the work. Watch what you think and choose which thoughts you follow. Watch what you say by owning your wins instead of swatting away credit. And watch what you do by carrying yourself in an open way instead of shrinking. Quieting the negative self-talk underneath all of it is what keeps the progress from leaking back out.
How do you get self confidence when you have none?
Start smaller than feels impressive. Catch the story your brain repeats and swap in a kinder one, take one compliment without deflecting, and reset your posture before something that scares you. Then pick one thing you've been avoiding and take a single step, before you feel ready.
Why does my confidence disappear when something goes wrong?
If your confidence is tied to feeling good, it rises and falls with your mood, so a hard week or tough feedback can drop it. Confidence built on self-trust holds up better, because it rests on evidence that you'll show up for yourself rather than on how you happen to feel that day.
Is confidence a feeling or a skill?
A bit of both, though the lasting kind leans toward skill. Confidence includes how you feel, but the version that survives hard days is a habit you build through small, repeated actions. That's good news, because a habit is something anyone can practice.
