Dr Tara Swart is a neuroscientist, former psychiatrist, and senior lecturer at MIT Sloan. Her episodes on The Diary of a CEO are among the most revisited in the show's history — because she does something rare: she explains the science behind concepts like manifestation, visualisation, and intuition in a way that even sceptics can't dismiss.
Before Dr Swart appeared on The Diary of a CEO, manifestation was largely associated with wishful thinking and pseudoscience. Tara bridged the gap between neuroscience and self-help by explaining the actual brain mechanisms that make visualisation and intention-setting effective — not magic, but selective attention and neuroplasticity.
Steven Bartlett has openly credited Dr Swart as one of the guests who most influenced his personal thinking, and her concepts — particularly the action board — have become staples of the DOAC community.
The foundation of Dr Swart's argument rests on a well-established neuroscience concept: the reticular activating system (RAS). This is the part of your brain that filters the millions of pieces of information hitting your senses every second and decides what reaches your conscious awareness.
"Your brain is constantly filtering reality. It lets in what it believes is important to you. If you prime your brain with a clear vision of what you want, you literally start seeing opportunities that were always there but invisible to you before."
This is why, Tara explained, when you decide to buy a specific car, you suddenly see that car everywhere. The cars were always there — your brain just wasn't flagging them as relevant. The same principle applies to career opportunities, relationships, and creative ideas.
Dr Swart drew a sharp distinction between passive vision boards (cutting out pictures and hoping) and what she calls an "action board." The difference is critical:
The neuroscience behind the action board works on three levels:
"An action board works not because the universe delivers things to you. It works because your brain starts delivering relevant information to your conscious awareness — and then you act on it."
Tara shared her own story of creating an action board that included a picture of a specific apartment in London. Within months, a chain of events — conversations, introductions, decisions she might not have otherwise made — led her to living in that exact building. Not magic. Primed attention leading to aligned action.
One of the most empowering sections of the episode was Dr Swart's explanation of neuroplasticity — the brain's ability to physically reorganise itself based on experience, thought patterns, and deliberate practice.
Key points she made:
"People think change is about willpower. It's not. It's about repetition. Your brain doesn't care about your intentions — it cares about what you actually do, repeatedly, over time."
Dr Swart broke down the brain's key neurochemicals and how they affect daily performance, mood, and decision-making:
Understanding these chemicals, Tara argued, gives you a practical toolkit for managing your mental state. Feeling unmotivated? You probably need dopamine — set a small, achievable goal. Feeling anxious? Your cortisol is likely elevated — go for a walk, breathe deeply, or call someone you trust.
Dr Swart made a compelling case that intuition — often dismissed as irrational — is actually the brain's most sophisticated processing system. Your subconscious mind processes approximately 11 million bits of information per second. Your conscious mind handles about 40. Intuition is the subconscious delivering conclusions that your conscious mind hasn't caught up to yet.
"That 'gut feeling' isn't mystical. It's your brain processing patterns from decades of experience faster than your conscious mind can articulate. Ignoring it is ignoring your most powerful analytical tool."

"The most successful people I've worked with don't have better brains. They have better brain habits."
"Stop waiting for motivation. Create the conditions — sleep, movement, visualisation, action — and motivation follows. It's an output, not an input."
Dr Tara Swart's appearance on The Diary of a CEO remains one of the most intellectually rigorous and practically useful episodes in the show's catalogue. She turned abstract self-help concepts into concrete, evidence-based strategies that anyone can implement. Whether you're sceptical about manifestation or already a believer, this episode will sharpen your understanding of how your brain actually creates your reality — and how to take control of that process.
