The most powerful thing I have learned as a therapist—something many ancient spiritual practices have always understood—is that your beliefs create your reality.
The brain is constantly bombarded with thousands of pieces of information—biological, physical, social–much of which is ambiguous and open to interpretation. To make sense of this flood of stimuli, it relies on a framework: your beliefs. Our beliefs function as the roadmap for reality.
Is your friend actually annoying, or are you just hungry? Is your day really off to a bad start, or are you just sleep deprived?
If your roadmap is shaped by negative beliefs, then that’s the reality you’ll experience. Your friend is annoying. Your day already sucks. Your coworker's coldness means he disapproves of you. Your friend didn’t say “hi,” he must be mad at you. Your boss is punishing you by asking you to stay late.
Conversely, if your roadmap is shaped by positive beliefs, then you’ll interpret those same situations differently. You recognize that hunger and tiredness are fueling irritation. Your coworker is likely upset for their own reasons. Your friend didn’t say “hi” because they didn’t see you. Your boss asked you to stay late because they trust you to get things done.
It doesn’t feel like an interpretation. It feels like objective reality. But it isn’t.
This assumption is the foundation for many theories of psychotherapy: how does our “unconscious understanding” of the world or “automatic beliefs” lead our brain to perceive the world in the way it does.
Generally the idea is, if we were raised by loving and validating parents that supported our individual identity, emotions and experiences, then we learn to trust ourselves and the world. If we were raised by parents that were stressed and burnt out, emotionally absent, and/or had their own unresolved trauma, they may unintentionally, or even intentionally, conveyed that our needs are burdensome and our emotions are invalid. We then constantly doubt ourselves, believe the world is dangerous, love is conditional, and only certain parts of us are acceptable.
These beliefs are so powerful that not only do they shape how we see the world, but they actually lead us into an existence that confirms them. The real tragedy is that when we see the world negatively, we are actually acting in ways that perpetuate that negativity.
When you’re suspicious of others, you go into situations closed off and people react negatively to your automatic mistrust of them. When you expect rejection and to not belong, you don’t put yourself out there or allow yourself to be vulnerable and seen by others. If people don’t see you, they can’t relate to you, or connect to you, and you end up getting left on the outskirts. When you judge or dismiss your feelings, then you don’t listen to your intuition and consequently are misled by others, leading you to be hurt, and then mistrust your feelings–and others– all over again.
None of this is in our conscious control. Our formation of beliefs is involuntary, and is a complicated amalgam of personal experiences, genes, and collective societal beliefs. But many of these beliefs are deeply entrenched and enduring, leading us to not only interpret, but also recreate the world based on these experiences. So deeply entrenched are these beliefs, that not only do ambiguous stimuli—but sometimes even clear contradictions— fall into the default (belief) category.
So in a sense, we create our own reality depending on our beliefs. This can be both liberating and devastating. It’s terribly painful to think we could be responsible for our own suffering. But it’s also extremely powerful to know that we can change things that we once felt we had no control over.
It's important to note that this doesn’t invalidate the very real pain of trauma, injustice, or adversity. It doesn’t deny the impact of others’ cruelty or systems of oppression. But it means we retain agency—we get to choose how we respond and what those experiences meant to us: will they crush us or will they motivate us.
We don’t choose our genetics, our family, or our society. We don’t choose our initial beliefs or reality.
But what we do have is free will. We do get to choose how we will spend every moment of our lives.
The hallmark of good mental health is psychological flexibility.
Psychology flexibility means not being married to the way our brains perceive the world. It means taking a step back and considering other options. It means noticing the “Negative Nancy Thought” or the scared feeling and deciding to try something new anyway.
And when you begin to change, the world begins to change with you. You find new people, have different experiences, and start to feel safer, more seen, and more authentically yourself.
This is the heart of Psychotherapy. At its core, therapy helps you create new roadmaps—rooted in self-trust, openness, and growth. You can't control everything that happens, but you can learn to see and respond to the world differently. And in doing so, you create the reality that you want.
