INSIGHT

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.
INSIGHT

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.
ADVICE

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.
