What if the key to lasting behavior change, personal growth, and feeling more confident wasn't about setting epic goals—but running tiny experiments? In this mind-expanding episode, Angela sits down with Anne-Laure Le Cunff—founder of Ness Labs and author of Tiny Experiments—to explore how small tests rooted in curiosity can lead to powerful transformations in every area of your life.

From alcohol-free living to productivity hacks, sleep rhythms, and navigating health advice in the age of information overwhelm, this conversation will shift your perspective on goal-setting and self-optimization. Anne-Laure shares why most people get stuck trying to rationalize decisions instead of following data from their own lived experience—and how becoming an “agent of change” helps us reclaim control in an ever-changing world.

 

KEY TAKEAWAYS:

• The Problem with Pros & Cons Lists: We often use them to justify decisions we've already made rather than explore truth objectively.

• How to Run Tiny Experiments: Focus on curiosity, one measurable variable, and a fixed timeframe to discover what truly works for you.

• Why Habit Challenges Often Fail: Without curiosity and internal motivation, behavior doesn’t shift—experimentation creates sustainable change.

• The Plus-Minus-Next Framework: A simple self-reflection tool to assess what’s working, what’s not, and what to try next—without judgment.

• Letting Go of Epic Goals: Big dreams can be paralyzing—often, purpose and passion emerge through action, not planning.

• Becoming Your Own Scientist: Whether it’s a new supplement, workout time, or meditation habit, take charge with your own data-informed experiments.
