Episode notes
Reclaim Your Power By Shifting Focus
- Stop giving your power to other people's opinions and moods and reclaim your energy.
- Focus on daily actions that make you proud and respond to your emotions like an adult.
Treat Meaning As A Workable Project
- Young adults often lack any baseline sense of life's meaning, which drives anxiety and depression.
- Arthur Brooks recommends treating meaning as a project: ask why you're alive and what you'd die for to start building purpose.
Use Vigorous Exercise To Boost Brain Health
- Do vigorous exercise to raise lactate and BDNF, supporting neurogenesis and hippocampal growth.
- Prioritize high-intensity sessions because lactate spikes for ~20–25 minutes and signals brain-protective pathways.
