Sometimes we know that a belief is no longer helping us—and still cannot seem to let it go.
It may sound like:
-
“I have to handle everything myself.”
-
“If I make a mistake, people will think I am incapable.”
-
“If I set a boundary, they will leave.”
-
“I need to know exactly what will happen before I begin.”
-
“If I cannot do this properly, there is no point in trying.”
These beliefs are often described as rigid or limiting. But that language can miss something important: many of them developed for a reason.
A belief may have helped you avoid criticism, stay connected to important people, manage uncertainty, prepare for danger, or function in an environment that did not understand your needs.
The problem is not necessarily that the belief exists. The problem is that it may continue making decisions long after the circumstances around it have changed.
Changing an old belief does not always mean arguing with it until it disappears. Sometimes the more helpful goal is to understand what it has been doing for you and create more choice in how you respond.
Cognitive flexibility and psychological flexibility
Cognitive flexibility involves being able to consider different perspectives, explanations, or strategies.
For example:
“If I need help, it means I have failed.”
might shift toward:
“Needing help may mean that the situation requires more support than one person can reasonably provide.”
Psychological flexibility is broader. It means being able to notice a thought, emotion, bodily reaction, or urge without automatically allowing it to determine what happens next.
You may still feel uncomfortable asking for help and decide to ask anyway because your health, relationships, or capacity matter to you.
The old thought may remain present. It simply has less control.
The following questions can help you approach these patterns with more curiosity and less self-criticism.
1. What did this belief once protect me from?
Before trying to change a belief, ask what purpose it may have served.
Perhaps staying quiet helped you avoid conflict. Perfectionism may have protected you from criticism. Doing everything yourself may have reduced the risk of disappointment.
Understanding the original function of a belief does not mean you have to keep following it. It helps you approach the pattern with compassion rather than treating it as evidence that something is wrong with you.
2. What does following this rule help me avoid now?
Old beliefs often continue because they reduce discomfort in the short term.
Avoiding a difficult conversation may reduce anxiety. Refusing help may protect you from feeling vulnerable. Waiting until you are completely prepared may reduce the possibility of making a visible mistake.
The relief is real—but it may come with a cost.
You might avoid embarrassment and also miss opportunities. You may avoid disappointment and also become isolated. You may maintain control and become exhausted.
3. Is the current situation the same as the one where this belief developed?
Sometimes our minds and bodies react to what is happening now as though it is identical to what happened before.
Ask:
-
Is this person behaving like someone from my past, or am I expecting the same outcome?
-
Is this environment actually unsafe, or does it feel familiar?
-
What evidence suggests that the current situation may be different?
-
What evidence suggests that caution is still needed?
The goal is not to dismiss your instincts. It is to distinguish current information from old expectations as clearly as possible.
4. Is this a belief problem—or do I need better support?
Not every difficulty with change is caused by rigid thinking.
A need for routine, advance notice, written instructions, sensory support, or additional processing time may reflect a legitimate need rather than a mindset problem.
Executive-function demands, pain, fatigue, trauma responses, sensory overload, and uncertainty can all make shifting more difficult.
Instead of asking only, “How do I make myself adapt?” consider:
“What conditions would make this more manageable?”
Sometimes the most flexible response is changing your strategy. Sometimes it is asking the environment to become more accessible.
5. What is one small experiment I could try?
Large changes can feel overwhelming and may reinforce the belief that change is unsafe.
Choose one small, specific experiment instead.
If the belief is “I have to do everything myself,” you might ask a reliable person for help with one task.
If the belief is “I must do this perfectly,” you might create a deliberately imperfect first draft.
If the belief is “My needs are too much,” you might name one small preference in a safe relationship.
The goal is not to prove the belief wrong. It is to gather information about what happens when you respond differently.
6. What would help my nervous system stay supported?
Trying something new may bring emotional or physical activation, even when the situation is reasonably safe.
Before, during, or after the experiment, consider what helps you feel more present and grounded.
This might include:
-
slowing down;
-
movement or stretching;
-
rhythm or music;
-
grounding through the senses;
-
breathing in a way that feels comfortable;
-
speaking with a trusted person;
-
body doubling;
-
using a visual plan;
-
or scheduling recovery time afterward.
Support does not eliminate discomfort. It can make the discomfort manageable enough for a new experience to occur.
7. What response reflects what matters to me now?
Old beliefs often focus on avoiding danger, criticism, rejection, or failure.
Psychological flexibility also asks what you want to move toward.
You might value connection, honesty, creativity, health, fairness, rest, courage, or self-respect.
A values-based response is not always the easiest response. It is the one that best reflects the person you want to be in the current situation.
Sometimes that means compromising.
Sometimes it means asking for help.
Sometimes it means changing your plan.
Sometimes it means maintaining a boundary, even when another person is disappointed.
Flexibility is not self-abandonment
Psychological flexibility does not mean becoming endlessly adaptable.
It does not require you to ignore your limits, tolerate harmful behaviour, mask who you are, or become more convenient for other people.
Healthy flexibility includes both the ability to change direction and the ability to remain firm.
The question is not:
“How can I force myself to be less affected?”
It is:
“How can I create more freedom to respond in a way that respects both what matters to me and what I genuinely need?”
Old beliefs may continue to show up, especially during stress.
Progress may look less like never having the thought again and more like noticing it sooner, understanding what it is trying to do, and realizing that it does not have to take over every decision.
When these patterns are deeply rooted, connected to trauma, or difficult to approach without becoming overwhelmed, therapy can offer support in understanding their origins and practising new responses at a manageable pace.
