1. James Clear on the Tiny Habits That Actually Stick

2h 11m · December 2025

Watch James Clear on the Tiny Habits That Actually Stick on YouTube

James Clear explains how to make a habit easier to repeat when life gets busy. His advice starts with the first few minutes: choose a manageable beginning, prepare your surroundings, and find a version of the activity you enjoy.

Key takeaways

  • Make the start small. Read one page or put on your running shoes. A manageable beginning gives the habit a place in your day.
  • Choose a version you enjoy. Lifting, climbing, and kayaking can serve the same goal. Pick an activity you want to return to.
  • Prepare for next time. Set out your clothes or leave a first sentence ready. Remove a decision before it becomes an obstacle.
“Join groups where your desired behavior is normal.”

2. Anna Lembke on Dopamine, Cravings, and Digital Habits

1h 46m · January 2026

Watch Anna Lembke on Dopamine, Cravings, and Digital Habits on YouTube

Anna Lembke explores why easy rewards can become hard to put down. She connects cravings with stress and explains how planning boundaries in advance can help interrupt an automatic habit.

Key takeaways

  • Notice the cost. Look at what scrolling displaces: sleep, work, or time with people. Consequences tell you more than screen time alone.
  • Add a small barrier. Keeping your phone in another room creates a pause between feeling an urge and acting on it.
  • Plan for stressful moments. Choose an alternative before a difficult day makes the familiar habit appealing again.
“Because if we wait till that moment to decide whether or not to do something that's hard, we almost always choose not to do it.”

3. Louisa Nicola on Exercise and Brain Health

2h 5m · February 2026

Watch Louisa Nicola on Exercise and Brain Health on YouTube

Louisa Nicola discusses how movement, learning, and everyday routines may support brain health. The conversation offers questions worth exploring, while its strong claims about preventing Alzheimer’s need to be treated carefully.

Key takeaways

  • Consider different kinds of movement. Nicola discusses strength training, aerobic exercise, and the distinct questions each raises about brain health.
  • Look beyond the workout. Notice long stretches spent sitting. A training session is only one part of the day.
  • Keep learning something. Reading, practicing a skill, and demanding conversations give your mind regular work to do.
“We can build reserve in a number of different ways.”

4. Michael Breus on Better Sleep and Night Waking

2h 24m · February 2026

Watch Michael Breus on Better Sleep and Night Waking on YouTube

Michael Breus looks at the habits surrounding bedtime and the worry that can build after a poor night. His most useful suggestions concern winding down, noticing your sleep patterns, and recognizing when persistent symptoms need assessment.

Key takeaways

  • Give bedtime a transition. Finish tasks, complete your usual hygiene routine, then leave time for something calming.
  • Notice your caffeine pattern. Track when you drink it and whether the amount rises after a bad night.
  • Reduce the clock-watching. Calculating how little sleep remains can add anxiety to an ordinary night waking.

2h 31m · December 2025

Watch Allison Wood Brooks on Better Conversations on YouTube

Allison Wood Brooks treats conversation as a skill you can practice. Her TALK framework covers topics, asking, levity, and kindness, with examples of how small choices help people feel heard and stay involved.

Key takeaways

  • Ask a follow-up. Stay with a detail the person just shared before moving to your own story.
  • Prepare one thoughtful opening. Recall a project, move, or interest they mentioned. A few seconds of preparation can help.
  • Let depth develop. Notice whether someone wants to say more. Give a personal conversation time to grow.
“Good conversation requires mutual engagement.”

6. Chris Williamson on Goals and Enjoying Your Life

2h 27m · December 2025

Watch Chris Williamson on Goals and Enjoying Your Life on YouTube

Chris Williamson examines how the pursuit of success can crowd out the life you hoped it would create. He offers practical questions about priorities, time, and the experiences you keep postponing.

Key takeaways

  • Make room for the goal. Name what will receive less time before adding another commitment.
  • Define a good year concretely. A few changes, such as more time with friends, can reveal what you actually want.
  • Count the hidden costs. Include your commute, evenings, and relationships when judging a new opportunity.
“Setting the bar unrealistically high does not increase your performance.”

7. David Bach on Saving, Debt, and Buying a Home

1h 49m · January 2026

Watch David Bach on Saving, Debt, and Buying a Home on YouTube

David Bach explains his approach to regular saving and automatic money routines. His discussion with Bartlett also surfaces the tradeoffs behind buying a home, paying down debt, and investing for the long term.

Key takeaways

  • Give savings a regular place. An affordable automatic transfer can make a decision easier to repeat.
  • Review recurring expenses. Look for subscriptions you no longer use and payments that continue mainly through habit.
  • Compare the full cost. Housing costs, debt interest, and flexibility belong alongside the appealing headline numbers.
“Your investments should be boring.”

8. Tristan Harris on AI, Jobs, and Human Relationships

2h 22m · November 2025

Watch Tristan Harris on AI, Jobs, and Human Relationships on YouTube

Tristan Harris argues that competition between AI companies rewards speed while leaving wider consequences unresolved. He examines jobs, safety tests, and chatbot relationships, and asks which choices people can still influence.

Key takeaways

  • Follow the incentives. Ask who benefits from a faster release and who carries the cost if it goes wrong.
  • Keep the test conditions visible. A result from a controlled safety test needs its setup and limitations attached.
  • Protect the learning path. If junior tasks are automated, how will newcomers gain the experience needed for senior work?
“we get to choose which of those futures that we want to have.”

9. John Kiriakou on the CIA, Influence, and Whistleblowing

1h 45m · January 2026

Watch John Kiriakou on the CIA, Influence, and Whistleblowing on YouTube

Former CIA officer John Kiriakou recounts intelligence work, recruitment, and his decision to speak publicly about torture. His career stories sit alongside broader allegations, so the distinction between firsthand experience and interpretation matters.

Key takeaways

  • Look for the specific motive. A recruitment story turns on one man’s wish to return to his family.
  • Check a familiar claim. Repeated institutional messaging still needs evidence, even when it begins to feel settled.
  • Separate capability from use. A described surveillance tool does not establish who was targeted or what actually happened.
“I love this country more than anything else in the world, and I wanted to do the right thing.”

10. Chris Koerner on Testing a Business Idea

2h 11m · December 2025

Watch Chris Koerner on Testing a Business Idea on YouTube

Chris Koerner explains how he tests business ideas through small offers and direct customer responses. He also describes an expensive failure, giving useful context to the work and risk behind apparently passive income.

Key takeaways

  • Test one clear offer. Define the customer, what they would receive, and the response that would justify another test.
  • Learn from existing businesses. Study pricing and offers to find questions worth testing in your own market.
  • Set a limit in advance. Decide how much time and money a test can use before optimism makes it expensive.
“I put a lot more emphasis on cash flow now in my 30s than I do on equity.”
