Brain Doctor: Why You Can't Stop Worrying Even When Nothing Is Wrong

This week I'm joined by David Rock, neuroscientist, author and founder of the NeuroLeadership Institute, and someone who has spent 28 years answering one of the most fascinating questions in science:Why do we do what we do? And how can understanding our brain change everything?
We explore human behaviour, the neuroscience of threat and reward, and what it really means to work with your brain rather than against it.
Dr. David Rock coined the term neuroleadership and is the Co-founder and CEO of the NeuroLeadership Institute (NLI). The Institute is a 23-year-old cognitive science consultancy that has advised over 50% of the Fortune 100. With operations in 24 countries, the institute brings neuroscientists and leadership experts together to make organisations better for humans through science.
What we explore together:
• Why the brain is always making a threat or reward decision

• What the SCARF model is and why it explains almost every difficult human interaction

• Why being interrupted feels physically painful and what your brain is actually doing

• How insights really work in the brain and why your best ideas come when you stop trying

• Why one negative comment can override dozens of positive ones and how to rewire that

• What sleep, glucose and rest actually do to your ability to think clearly

• Why status is one of the most powerful forces driving human behaviour and how to work with it

Love, Sarah Ann 💛
