What if the mistakes you’re trying so hard to avoid are exactly what your brain needs to change? Neuroplastician John Kennedy built the first targeted neuroplasticity training program for the Marine Corps, and he’s spent nearly 20 years helping Navy SEALs, Olympic athletes, and kids with autism rewire their brains. In this conversation, we get into why the struggle matters more than accuracy, how flow state actually works, and how anyone facing a career change or life transition can train their brain to adapt faster.
→ Why “it’s not the accuracy, it’s the struggle” is how your brain rewires fastest→ How an Olympic skier learned to see further down the hill at 100 mph (flow state, explained)→ How to use intentional practice to get ready for a new job, an interview, or any big transition→ What digital dementia is, and why the years before age seven matter so much→ Why boredom is brain training for kids and a gift for adults→ How the brain can rewire around strokes, concussions, and other damage

FAQ
Q: What is neuroplasticity?
A: Neuroplasticity is the brain’s ability to rewire itself by forming new connections, at any age. Whatever you repeat in thought, speech, or action, the brain gets faster and more efficient at. That includes rewiring around damage from strokes or concussions.
Q: Can you rewire your brain as an adult?
A: Yes. John Kennedy sees processing speed improve 10–20% in under an hour with his training exercises, because the brain starts rewiring during the exercise itself.
Q: What is digital dementia?
A: Researchers in South Korea found that children who used phones heavily from a very young age were showing dementia-like symptoms by their early twenties. They missed the window before about age seven, when the brain builds its foundational connections.
Q: How does neuroplasticity help with a career transition?
A: A new job or situation asks your brain to recognize a new pattern. Intentional practice speeds that up: anticipate the interview questions, picture the new role, and walk through what will be different.
