What you’ll learn:
- How David transitioned from gaming to healthcare through mission-driven insight
- The real story behind Calm’s evolution from sleep and meditation to global mental health
- Why David uses “battery level” as a tool for checking in at work
- How leaders can model vulnerability without sacrificing authority
- Why burnout stems from poor workload management, not just long hours
- The power of shared purpose in turbulent times
- How Calm uses rituals like Jay Shetty meditations and Zoom-free days to reinforce its culture
- Why sleep, diet, and presence are core to David’s leadership performance
- How transparency builds trust even when the news isn’t good
- Why the conversation around mental health needs to start at the top
Some takeaways:
➡️ Stress is not the problem. Unchecked, unacknowledged stress is. Good stress can fuel resilience and performance.
➡️ “How’s your battery?” is a more meaningful check-in than “How are you?”
➡️ Burnout often comes from lack of clarity and excessive task stacking, not too many hours.
➡️ Leaders must explain the why behind priorities and remove as much as they assign.
➡️ Transparency about culture survey results builds psychological safety.
➡️ Rituals like 90-second meditations help reset and re-center teams.
➡️ Leadership can be lonely. Trusted colleagues make a critical difference.
➡️ Presence matters more than hours. Back-to-back meetings are not a badge of honor.
➡️ Sharing your own mental health journey is not weakness. It’s how resilient teams are built.
➡️ “We take better care of our phone batteries than our mental health batteries.” Time to change that.
