Tim Cook reveals his 4 a.m. email routine that guided Apple for 15 years

Tim Cook, who has moved from CEO to executive chairman of Apple, reflected on a morning habit that defined his leadership. For the past fifteen years he rose just before 4 a.m., spent an hour reviewing user feedback emailed from around the globe, and then exercised before returning to work. He said the routine let him feel the "beating heart" of Apple’s customers and deepened his commitment to the company’s mission.

Cook’s description appears alongside a brief look at how other high-profile leaders manage their inboxes, from Mark Cuban’s public email scans to Uber’s Dara Khosrowshahi’s weekend messages and Airbnb’s Brian Chesky’s preference for calls over email. The piece underscores the personal discipline behind Apple’s growth through a pandemic, supply-chain challenges and the rise of AI. It highlights how direct customer insight can shape executive decision-making at a major tech firm.
