• How chronic stress hormones like cortisol erode self-control and make bad habits easier to repeat
• Why lapses in discipline are biological, not moral failures—and how that mindset shift reduces shame and rebound quitting
• How to design environments and routines so habits, not moment-to-moment willpower, do most of the heavy lifting
• A simple process to pick one area of your life, apply the science this week, and take one small, realistic action
• How to capture key insights in writing so your brain actually remembers and uses what you learned
