In this episode of On Purpose, Jay Shetty sits down with Mark Rober, the brilliant engineer, YouTuber, and creator whose experiments and inventions have inspired millions to rediscover their love for science and curiosity. Mark shares his journey from NASA engineer working on the Mars Curiosity rover to becoming one of YouTube's most beloved educators and innovators. (01:22) The conversation explores how Mark's mother's encouragement of creative thinking shaped his approach to life and work, leading to a career that seamlessly blends engineering precision with childlike wonder. (04:02) Together, Jay and Mark unpack the mindset of "thinking like an engineer," the importance of embracing failure as fuel for growth, and how staying curious as an adult can unlock extraordinary possibilities.
Mark Rober is an engineer, YouTuber, and inventor who worked at NASA for a decade, contributing to the Mars Curiosity rover before moving to Apple for five years in product design. He now reaches over 72 million subscribers through his YouTube channel, where he creates engineering experiments and educational content that makes science accessible and exciting. He's also the founder of Crunch Labs, a toy company that teaches engineering principles to children through hands-on monthly activities.
Jay Shetty is the host of On Purpose, one of the world's most popular podcasts focused on helping people become happier, healthier, and more healed. A former monk turned digital wellness expert, Jay has built a global community through his content that blends ancient wisdom with modern science to help people live more meaningful lives.
Mark explains that thinking like an engineer means being unafraid of failure and viewing setbacks as valuable learning opportunities rather than personal inadequacies. (11:48) He describes how at NASA, breaking things during testing is actually encouraged because "if you're not breaking stuff, it means you're not really testing the limits." When failures occur, engineers don't internalize them as personal shortcomings but get excited to learn "one more way not to do a thing." This mindset creates resilience and curiosity rather than fear, similar to how toddlers approach learning to walk or how players approach video games where dying doesn't discourage them from trying again.
Rather than forcing an either-or choice between passion and practical career moves, Mark demonstrates the power of pursuing both simultaneously. (20:39) He worked at NASA for a decade and Apple for five years while building his YouTube channel on nights and weekends, only quitting his job when he had 10 million subscribers. This approach allows you to test whether you truly love your passion project (since you're doing it when it's inconvenient) while maintaining financial security. Mark advises giving everything you have to whatever's in front of you, then evaluating your next options with all the new facts and experience you've gained.
Mark breaks down the engineering design process as a framework for tackling any challenge: identify your end goal, break it down into steps, know what you don't know, and test iteratively. (24:50) Just as NASA tests Mars rover components repeatedly before launching to space, you should prototype and test your ideas in life rather than trying to build the perfect final version immediately. This means setting low bars initially, being willing to fail multiple times, and learning from each iteration. Mark applied this even to dating, doing 30 FaceTime dates in 30 days to practice and learn before meeting his current partner.
Mark identifies his ability to say no as his "superpower" for maintaining creative quality and avoiding burnout. (61:21) He's consistently uploaded only one video per month for 14 years, even when the YouTube algorithm favored daily content. His rule is simple: unless something is an "absolute hell yes," he doesn't even consider it. This laser focus allows him to put all his energy into fewer, higher-quality projects rather than diluting his efforts across many mediocre ones. The principle applies beyond content creation to relationships and life choices - having depth with fewer things creates more fulfillment than spreading thin across many.
Mark explains that creativity and learning start with simple curiosity and observation of the world around you. (72:23) He shares how even noticing something as simple as an unusual pipe on a building can drive him to investigate and learn something new. The key is asking "why?" about everyday things and being genuinely driven to find answers. Mark describes himself as a "fire starter" who ignites curiosity in others rather than teaching everything - the goal is to get people addicted to the feeling of learning something new. This approach treats learning like the scientific method, where the most exciting phrase isn't "eureka" but "that's interesting."
