How to Change the Hidden Beliefs Controlling your Life | Jackie Brennan | TEDxBlack Mountain
The biggest prison in the world has no bars, no guards and billions of inmates. It's the human mind.
In this powerful TEDx talk, Jackie Brennan tells the unforgettable story of Mahine, a rare white tiger who never left the corner of her cage, even after it was gone. That metaphor becomes personal as Jackie shares her lifelong fear of heights and how one bridge, one belief, and one moment transformed everything.
With warmth, wit, and wisdom, Jackie breaks down the invisible autopilot programmes that hold us back and shows how small brain hacks, like visualisation, posture, and even singing, can rewire your thinking. Her message is simple and profound: the door to your cage has always been open.
So what if the only thing standing between you and your best life is a belief that was never true?
“Crossing that bridge wasn’t just about fear — it was about finally letting go of the crap that held me back.” – Jackie Brennan
Jackie Brennan believes the greatest power we
possess is the ability to change our own lives—once
we truly understand how the mind works. Having
experienced burnout firsthand, she developed a deep
fascination with the science of human behaviour and
what drives us.Today, Jackie helps individuals and organisations
break free from outdated, autopilot subconscious
patterns and tap into the hidden potential that’s been
there all along. For her, understanding the mind isn’t
just an advantage, it’s the ultimate game-changer. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

- 11:32O nível do mar sobe há décadas. Como minimizar suas consequências? | Valdenira Santos | TEDxAmazôniaQuando pensamos em mudanças climáticas, nos vem à mente altas temperaturas, secas e enchentes extremas, aumento de furacões e incêndios. Poucos se dão conta de um movimento quase imperceptível que gera consequências drásticas: o aumento do nível do mar, que atinge mais de 2 bilhões de pessoas que vivem em zonas costeiras. A geóloga Valdenira Santos nos traz encaminhamentos urgentes para evitar catástrofes iminentes. Valdenira é uma geóloga apaixonada pela Amazônia Costeira que dedica sua vida a desvendar os mistérios das transformações dos ambientes costeiros no encontro da vasta foz do rio Amazonas com o mar. Com um doutorado em Geologia e Geofísica Marinha e uma carreira dedicada à pesquisa, ela tem contribuído largamente para a compreensão da dinâmica e dos desafios da região. Seus estudos pioneiros sobre a pororoca na foz do Amazonas são um marco na pesquisa científica brasileira. Valdenira é uma voz ativa na defesa do uso racional e sustentável dos ecossistemas costeiros e marinhos da Amazônia e, através do Observatório Popular do Mar-OMARA, ela mobiliza a sociedade civil para a conservação dos oceanos.
