Episode notes
Thoughts Restructure Your Brain
- Thoughts literally restructure your brain through neuroplasticity, so mental habits shape neural wiring.
- Lee Warren calls deliberate change “self-brain surgery” because intentional thinking makes structural brain changes.
Your Brain Filters Reality
- Your reticular activating system filters what you notice based on your expectations and focus.
- You see more of what you look for, which shapes your perceived reality and attention.
Rehearse New Responses
- Plan and rehearse a different response before a trigger occurs to rewire your habitual reaction.
- Repeat the new response to get positive reinforcement and create a new neural pathway.
