Self-doubt is often treated as a flaw to eliminate. But in a conversation with Mel Robbins, behavioural reseacher Dr Shadé Zahrai argued that the better goal is not to erase doubt, but to prevent it from taking over. Her book “Big Trust” offers a proven framework for breaking the cycle of self-doubt and building deep, unshakable self-trust.

“You are worthy just by existing.”

Speaking on the podcast, Dr Zahrai outlined a four-part framework for building self-confidence: acceptance, agency, autonomy, and adaptability. Her core point was that confidence is not a personality trait reserved for a lucky few. It is something that can be strengthened by learning how to relate differently to uncertainty, criticism, and the inner voice that says you are not enough.

“You don’t have to eliminate the doubt. You just have to strengthen parts of yourself that allow you to move through it.”

Acceptance

Acceptance is the starting point: acknowledging that you are a work in progress and that your worth is not something you have to earn first. Dr Zahrai frames this as stopping the habit of self-rejection before anyone else can reject you. In practice, it means noticing self-critical thoughts without turning them into proof that you are defective.

Agency

Agency is the sense that you can act, influence outcomes, and learn what you need to learn along the way. Dr Zahrai’s point is that confidence grows when you trust that you can do the thing, even if you do not yet know how. It is less about feeling fully ready and more about believing you can take a next step and figure it out.

Autonomy

Autonomy is about having a real sense of control over your choices and not outsourcing your life to other people’s opinions. In the episode, this shows up in her focus on boundaries, delaying automatic yeses, and making decisions that are aligned with your own values rather than approval-seeking. It is the part of the framework that helps people stop living as if everyone else gets a vote on their worth.

Adaptability

Adaptability is the ability to move through uncertainty, change, and emotional discomfort without collapsing into self-doubt. Dr Zahrai treats it as more than “being flexible”; it is resilience in action, especially when plans change or life gets messy. The idea is that confident people are not unaffected by setbacks — they recover, adjust, and keep moving.

How they work together

Taken together, the four attributes describe a system for turning self-doubt into something manageable. Acceptance keeps doubt from becoming self-hatred, agency keeps it from becoming paralysis, autonomy keeps it from becoming people-pleasing, and adaptability keeps it from becoming fragility. That is why the framework is presented as a way to build self-trust rather than chase perfection.

One of the episode’s central ideas was that self-doubt becomes most damaging when it is internalized. Dr Zahrai used a simple visual metaphor to explain the difference between letting doubt sit lightly on the surface versus allowing it to sink into identity. In her telling, doubt is manageable when it is treated like a passing thought. It becomes debilitating when people begin to interpret it as evidence of their worth.

“We don’t see the world as it is. We see the world as we expect it to be.”

That distinction, she said, helps explain why so many high performers still struggle with insecurity. Success does not necessarily eliminate self-doubt. In some cases, it can intensify it, because the stakes feel higher and the fear of falling short becomes more pronounced. Dr Zahrai’s argument was that the issue is not the presence of doubt, but the way people respond to it.

A substantial portion of the discussion focused on self-acceptance. Dr Zahrai described a set of common patterns that emerge when people do not fully accept themselves: the pressure to prove, the likability trap, shrinking away from opportunity, and the impulse to tear others down. Those patterns, she suggested, can shape careers, relationships, and everyday decision-making in ways that are easy to miss because they often feel normal.

“People who struggle with self-acceptance tend to identify with their jobs.”

Rather than offering vague encouragement, the episode emphasized small behavioral shifts. One recommendation was to replace reflexive apologies with appreciation, changing phrases like “sorry I’m talking too much” into “thank you for listening.” Another was to pause before saying yes, especially for people who chronically overcommit. Dr Zahrai also urged listeners to take up hobbies, arguing that interests outside work help separate identity from performance and restore a sense of self beyond achievement.

“Attention is such a superpower.”

The interview also challenged the usefulness of positive affirmations for people with low self-esteem. According to Dr Zahrai, affirmations can backfire when they are too far removed from how a person actually sees themselves. A more effective approach, she said, is to build self-acceptance through actions that are believable, practical, and repeated.

“If you struggle with self-acceptance and self-esteem, using positive affirmations backfires and makes you feel worse.”

The episode ultimately framed confidence as something more grounded than self-help slogans suggest. It is built through attention, repetition, and the willingness to stop treating every doubt as a truth. Dr Zahrai’s message was clear: the goal is not perfection, but movement.
