Overcoming Limiting Beliefs & Breaking Free from Self-Doubt

Imagine that the voice saying “I’m not good enough,” “I can’t do this,” or “What if I fail?” isn’t a permanent truth about who you are.

Overthinking and self doubt may be the result of experiences, social messages, repeated thoughts, and behaviours that have gradually become familiar.


From my hypnotherapy and coaching perspective, we can think of these patterns as deeply learned associations


Your subconscious mind doesn’t necessarily ask whether a belief is objectively true, it can respond to what has been repeated, emotionally reinforced, and practised.

And this is where psychology and behavioural science become particularly interesting.


Research on self-efficacy suggests that our beliefs about our ability to perform a task are influenced by previous accomplishments, observing others, social persuasion, and our emotional and physiological responses. A large meta-analysis of academic self-efficacy research found evidence supporting these different sources of self-efficacy. 

In other words, what you repeatedly experience, what you repeatedly hear from others, and what you repeatedly do can influence what you come to believe you are capable of.


1. Social influence: whose voice became your inner voice?

Self-doubt doesn’t always begin with us.

Sometimes it begins with something someone else said:

“You’re not confident.”

“You’re not academic.”

“You’re too sensitive.”

“People like you don’t succeed at that.”

“You always give up.”

Repeated social messages can become part of the framework through which we interpret ourselves.

Research into stereotype threat provides an important example of how social expectations can influence performance. Meta-analyses have found that awareness of negative stereotypes can, under some conditions, impair performance, although the size and reliability of these effects vary across contexts and studies.

This gives us an important coaching question:

“Is this actually my belief—or is it a belief I learned from someone else?”


2. Self-doubt can influence behaviour and behaviour can reinforce self-doubt


Imagine someone who believes:

“I’m not confident.”

They may avoid speaking up.

Because they don’t practise speaking up, they gain fewer experiences of success.

Those missed experiences then appear to confirm the original belief:

“See? I’m not confident.”

This can create a self-reinforcing cycle:

Belief → emotion → behaviour → experience → belief

The encouraging part is that the cycle can also work in the opposite direction:

New belief → new behaviour → new experience → evidence of capability → stronger self-belief

Research on self-efficacy supports the importance of actual performance experiences in developing confidence in one’s abilities. 


3. Your brain learns through repetition—but repetition isn’t magic

It is tempting to say that simply repeating positive affirmations will “reprogram the subconscious.” The science is more nuanced.

What has stronger behavioural evidence is repeated practice combined with specific action.

For example, instead of simply saying:

“I am confident.”

you could practise:

“When I notice myself holding back, I will take one small step forward.”

This brings us to a particularly well-researched technique: implementation intentions.


4. Turn intention into an “if–then” behaviour

Rather than relying on motivation in the moment, create a specific plan:

“If X happens, then I will do Y.”

For example:

  • If I notice myself overthinking before speaking, then I will take one breath and speak within five seconds.

  • If I hear myself saying “I can’t,” thenI will ask, “What is one thing I can try?”

  • If I make a mistake, then I will identify one thing I learned rather than attacking myself.

A major meta-analysis covering 94 independent tests found that implementation intentions had a meaningful positive effect on goal attainment, with evidence that these plans can make goal-directed responses more accessible and automatic. 
More recent research examining 642 independent tests also found implementation intentions were effective across cognitive, emotional, and behavioural outcomes, with stronger effects when plans used an explicit if–then structure and were rehearsed. 

5. Practice creates new evidence

One of the most powerful ways to challenge self-doubt is not to argue with it—but to collect evidence against it.

If your old belief is:

“I can’t handle difficult conversations.”

Don’t demand that yourself suddenly believe:

“I am amazing at difficult conversations.”

Instead:

“I can practise having difficult conversations.”

Then have one.

That experience becomes new evidence.

Do it again.

And again.

Over time, you’re no longer asking yourself to believe something without evidence. You’re giving your brain new experiences from which to build a different belief.


6. Stress can change how we perform

Self-doubt isn’t simply a thought. When we perceive a situation as threatening, our emotional and physiological responses can also influence how we perform.

Interestingly, research suggests that changing how people interpret physiological stress responses can sometimes improve performance. A 2024 meta-analysis of randomized controlled trials found small but significant improvements in task performance from stress-arousal reappraisal and stress-is-enhancing interventions, although the researchers emphasized that these approaches are not “silver bullets.” 

So instead of:

“My heart is racing. I’m going to fail.”

you might practise:

“My body is preparing me to perform.”

The objective isn’t to pretend anxiety doesn’t exist. It’s to change the meaning you attach to the experience.


7. Be careful with the “just think positively” approach

This is where the science gives us an important reality check.

Growth-mindset interventions have received considerable attention, but large reviews have found that their effects on academic achievement are generally small and inconsistent, particularly in higher-quality studies. 

So the message isn’t:

“Think differently and your life will magically change.”

It’s:

“Beliefs can influence behaviour, but lasting change usually involves beliefs + behaviour + experience + environment.”

That distinction makes the approach both more credible and more empowering.


8. A practical way to break the cycle

Try this five-step process:

Notice → Question → Reframe → Act → Record


Notice:


What does my inner critic say?

Question:


Where did I learn this? Is it completely true?

Reframe:


What is a more realistic and useful belief?

Act:


What tiny behaviour would demonstrate that new belief?

Record:


What happened? What did I learn?

You’re gradually moving from:

“I need to feel confident before I act.”

to:

“I can act while I’m uncertain—and allow confidence to develop through experience.”

A final hypnotherapy-style reflection

Take a slow breath.

And consider the possibility that you don’t need to fight the part of you that has been doubtful.

Perhaps that part developed for a reason.

Perhaps it was trying to protect you from rejection, embarrassment, failure, or disappointment.

You can acknowledge that intention without allowing the old pattern to run your future.

Because every time you respond differently, you create another experience.

Every time you practise a new behaviour, you create another piece of evidence.

And every time you challenge an old assumption with a real experience, you give yourself the opportunity to see yourself differently.


You are not required to become fearless.

You are learning to become less controlled by fear.

And sometimes, breaking free from self-doubt doesn’t begin with believing “I can do anything.”

It begins with something much smaller:

“Maybe I can try.”
