YouTube Growth: Start, Iterate, Persist

What idea have you been sitting on lately?

What’s been holding you back from starting?

Today, Jay sits down with engineer, innovator, and YouTube creator Mark Rober to explore the unexpected life experiences that shaped one of the internet’s most beloved minds. Mark shares the childhood moments that ignited his passion for building, breaking, and understanding how the world works, moments nurtured by a mother whose love, imagination, and encouragement helped lay the foundation for his life’s mission. He reflects on how her influence continues to ripple outward, inspiring millions of young people who learn, explore, and dream through his work today.

Jay and Mark explore the mindset that carried Mark from NASA engineer to innovative educator, unpacking what it really means to “think like an engineer:” experiment boldly, embrace failure, and treat every setback as an opportunity to learn. They follow Mark’s unusual pivots, from designing Mars rover hardware to crafting Halloween costumes, to ultimately shaping a career that blends curiosity, storytelling, science, and play. Together they reveal the deeper lessons behind Mark’s most viral experiments: why creativity thrives when we stay childlike, how passion reveals itself through repetition, and why the most meaningful work grows from genuine excitement rather than algorithms or expectations.

In this interview, you'll learn:

How to Think Like an Engineer

How to Stay Curious as an Adult

How to Follow Your Passion Practically

How to Build Ideas That Actually Work

How to Find Creativity in Everyday Life

How to Recognize Your Real Calling

How to Inspire Others Through Your Work

Keep following the questions that excite you, keep trying the things that scare you, and keep believing that you’re capable of far more than you realize. Your next breakthrough might be just one experiment, or one brave attempt away.

With Love and Gratitude,
