The stories you tell about yourself

“I’m not a numbers person.” Some beliefs about yourself were true once and are worth checking again.

The idea

Everyone carries stories about themselves: “I’m not creative”, “I’m bad with money”, “I’m not a leader”, “I always mess up interviews”. Some of these stories are accurate. Many were true once, in a particular situation, and have simply never been checked since.

These beliefs matter because they shape what you try. If you believe you are “not a numbers person”, you avoid anything with numbers, get no practice, and the belief confirms itself. The story becomes a fence you built around yourself years ago.

Checking an assumption is simple, if uncomfortable: find where it came from, look for evidence against it, and run a small test. You do not have to replace it with an equally strong positive story. “I don’t know yet” is often the most honest update.

Why it matters

Outdated beliefs about yourself quietly remove options you never consider. Updating even one can open a path — a subject, a job, a role — that was closed only in your head.

See it happen

Daniela has always said she is “terrible at public speaking” because she froze during a school presentation at fourteen.

The first read

She has known this about herself for years and avoided speaking ever since, so it feels like a settled fact about who she is.

With this idea

At thirty-two, she notices the belief comes from one bad day as a teenager. She tests it by giving a two-minute update at a team meeting. It is nerve-wracking but fine. She updates the story to “I get nervous, and I can do it”.

What changed

She traced an old belief to its source and tested it instead of obeying it.

Easy to get wrong

• Swinging to an equally untested positive story. The goal is an accurate belief, not a flattering one.
• Dismissing all self-beliefs as false. Some are accurate and useful — the point is to check, not to reject.

Different perspectives

Reasonable people disagree here. None of these is presented as the final word.

Beliefs about ability shape effort

Research on mindset suggests that believing an ability can grow makes people more willing to practise and persist, which can make the belief come true.

The effect is often small

Large reviews found quick mindset interventions have small average effects. Believing you can improve helps most when real practice and support follow.

What this rests on

Studied, still argued over. There is research here, and researchers disagree about how strong or general the effect is.

• Carol Dweck — research on mindset — Research on how believing that abilities can grow relates to learning and persistence. Large reviews found quick mindset interventions have small average effects, and the size of the effect is argued over.

Try it: Check one story

1. Write one sentence you often say about yourself that starts “I’m not…” or “I always…”.
2. Write when you first started believing it.
3. Write one piece of evidence against it, and one small test you could run.

Reflect

• Which beliefs about yourself might be outdated?
• What have you avoided trying because of a story you have never tested?

Use it in the coming days

Run your small test within the next two weeks and write in your journal what actually happened — without deciding in advance what it will prove.

Where to do it: My Journal

A test of an old belief is worth recording, so the evidence is there next time the story returns.
