Stop Faking It: How Building Confidence Actually Works When You’re Over 40

By Diana — Burned out at 42. Rebuilt by 44. The cool aunt energy you need. ·

I was sitting in a boardroom in downtown Chicago, clutching a lukewarm latte, listening to a 28-year-old consultant explain ‘synergy’ to me. I was 42, a VP of Marketing, and my heart was doing a weird, fluttery tap-dance against my ribs. I had the title, the salary, and the confidence that everyone told me I should have. But inside? I was a hollowed-out shell, terrified that if I stopped performing for five minutes, the whole facade would crumble.

That was the year I burned out. My body literally staged a coup, and I ended up in a neurologist’s office instead of the office.

Fast forward to today. I’m 47, I’m married to Paul—who is currently in the kitchen trying to convince his teenage son that documentaries about soil health are actually ‘cool’—and I’ve reclaimed my life. People often ask me, ‘Diana, how do I get that unshakable confidence you have now?’

Here’s the secret: Confidence isn’t a personality trait. It isn't a suit you put on. It’s a byproduct of evidence. And most of us are trying to build it the wrong way.

Stop Confusing Confidence with Performance

In my corporate life, I thought confidence was a performance. I had the power pose, the firm handshake, and the ability to pivot a strategy meeting on a dime. But that wasn’t confidence; that was a defense mechanism. I was terrified of being ‘found out,’ so I built an armor of competence.

True confidence, the kind that survives a divorce, career pivots, and the chaos of a blended family, isn’t about being the loudest person in the room. It’s about knowing that when things go sideways—and they will—you have the capacity to handle it. It’s the difference between ‘I can do anything’ and ‘I can handle whatever happens.’ See the shift? One is a fragile ego-trip; the other is a sturdy foundation.

The ‘Evidence Journal’ Method

If confidence is just evidence, we need to start collecting it. When we’re burned out or pivoting, our brains have a nasty habit of ignoring our wins and hyper-focusing on our gaps.

I want you to start an Evidence Journal. Every single night, before you scroll through social media or collapse into bed, write down three things you handled that day. They don’t have to be big.

When you track these, you’re training your brain to see your own competence. You aren't just ‘faking it until you make it’ anymore. You are meticulously building a case for your own capability.

Stop Waiting for the Feeling of Readiness

We love to wait for ‘readiness’ before we make a move. We want to feel confident before we start the business, before we ask for the raise, before we sign up for that class.

But confidence is the reward, not the entry fee.

Think about it: have you ever felt 100% ready for anything that actually mattered? Probably not. The messy, shaky, ‘I have no idea what I’m doing’ phase is where the growth lives. When you take an action despite the fear—when you sit in the discomfort of being a beginner again—you are proving to yourself that you don't need comfort to take action. That is the strongest form of confidence there is.

The ‘Cool Aunt’ Reality Check

Let’s get real for a second. We’re in our 40s. We don’t have time to play the ‘I’m not good enough’ game. If I can go from a frantic, high-stress VP to building a life where I actually like the person looking back at me in the mirror, you can too.

But you have to stop seeking external validation. If your confidence is tied to your boss’s praise, your partner’s approval, or the number of likes on your LinkedIn post, you are handing the keys to your self-worth to people who don't have your best interests at heart.

Action Plan for This Week

If you’re ready to actually build some internal stability, try this:

1. Audit your inputs: Who are you listening to? If your feed makes you feel ‘less than,’ unfollow. Your environment is 90% of your confidence struggle. 2. Do one ‘low-stakes’ scary thing: Send that email you’ve been drafting for three days. Say ‘no’ to a social invite you don’t want to attend. Prove to your nervous system that you can handle small amounts of friction. 3. Stop apologizing for your needs: Confidence starts in your language. If you find yourself saying ‘I’m sorry’ when you’re just stating a preference or a boundary, catch it. Stop. Breathe. Rephrase it as a statement.

Building confidence isn't about becoming a different person. It’s about shedding the layers of who you thought you had to be to survive. You’re already capable. You just need to stop looking at your reflection through the lens of other people’s expectations.

I’m curious—what’s one thing you’ve been putting off because you’re waiting to ‘feel’ confident enough? Hit reply to the newsletter or leave a comment below. Let’s talk about how to take the first step, even if your hands are shaking.
