In this video, I’m basically asking you to stop treating New Year’s resolutions like a personality test and start treating change like biology. I break down why goals fail (especially in January), and what’s actually happening in your brain when motivation spikes and then disappears. We talk about the “Fresh Start Effect,” why it feels so easy to reinvent yourself on January 1st, and why that feeling is temporary if your system stays the same. Then I go into the neuroscience side: dopamine isn’t just “pleasure,” it’s prediction and learning. When your brain stops getting the reward it expected, persistence collapses—so I explain dopamine prediction error and how to bridge reward to the present so your habits don’t rely on vibes. I also explain how habits become physical structures in the brain, which is why tiny actions done consistently beat willpower every time. Finally, I walk through what to do when you slip (without turning one off-day into a full identity crisis) and how to design a system that trains your attention and makes the “right thing” easier to repeat in real life.
