WHAT IT’S REALLY ABOUT
Dr Tara Swart on Neuroplasticity, Stress Resilience, Supplements and Vision Boards
- Swart describes her path from psychiatrist with a neuropharmacology PhD to executive coach, speaker and chief science officer at Heights, driven by a need for intellectual challenge and wider impact.
- She explains neuroplasticity through three mechanisms (neurogenesis, synaptic connection and myelination) and says new behaviours take weeks to months to embed, with a nine-month rewiring theory she hasn't shared before.
- Her stress-resilience advice centres on sleep, diet, hydration, exercise and mindfulness, plus quick resets like deep breathing, alternating near and far focus, and long-term practices like journaling, gratitude and time in nature.
- She discusses magnesium, probiotics, vitamin D and the gut-brain axis, arguing that stress depletes nutrients and that supplementation can help, though she says she doesn't notice a dramatic difference herself because of how she already lives.
- She presents vision boards as 'action boards' that work through selective attention and value tagging, and responds to Ali's confirmation-bias challenge by saying her hit rate is well above chance while conceding that bias exists.
IDEAS WORTH REMEMBERING
5 ideasNew habits become automatic through repeated practice, like wearing a path through a field.
Swart says a new pathway eventually reaches a tipping point where it overwrites old thinking. Simple habits take two to three weeks, emotional intelligence or creativity six to twelve months, and she theorizes nine months can rebuild neural pathways.
Match your learning goals to the difficulty level your brain can sustain.
She links myelination to things you're already good at, synaptic connection to things you could make an A grade with effort, and adult neurogenesis to very hard new skills like her golf attempt. She advises playing to strengths rather than trying to be good at everything.
Exercise and dark-skinned foods support neurogenesis.
Swart says aerobic exercise and anthocyanin-rich foods such as blueberries, purple sprouting broccoli, black beans, good coffee and dark chocolate over 80% cocoa help new neurons grow and connect. She adds that restarting exercise after a break can boost cell turnover more than steady exercise.
Stress makes people breathe shallowly, and deliberate breathing and focus shifts help reset the nervous system.
She suggests ten deep breaths, a sharp inhale followed by a long sigh, and alternating a minute of close-up looking with a minute of distant looking. She argues knowing you can shift your own state is empowering.
Journaling releases stress and also reveals patterns when reread.
Swart says getting thoughts out of your head lowers the cortisol load of holding them in, and rereading old entries shows patterns. Rereading her own journal revealed recurring muscle twitches and led her to identify magnesium deficiency from travel.
WORDS WORTH SAVING
5 quotesThere's a reason that our brains were wired in a certain way, and, and when we first became, you know, homo sapiens, we walked on the savanna.

If you really focus on doing this, in a nine-month period, which is the gestation period of a baby, so from fertilization to a newborn baby being born, you can essentially create a rebirth in your brain by rewiring your neural pathways.
— Dr. Tara Swart
Because I've trained myself in these, like, ways to reset my nervous system and longer term ways to build my resilience, I could find a way to not let you push me into that state, and knowing that, that I have the choice to do that, that's really, really empowering.
— Dr. Tara Swart
I didn't want to be asleep for the rest of my life. I wanted to be challenged and, um, do new and different things.

Play, play to your strengths. The neuroscience really supports that.
