For many CEOs, the workday begins before sunrise. Leaders like Nvidia’s Jensen Huang, Apple’s Tim Cook, and Disney’s Bob Iger have all said punishingly early mornings and rigid routines are their preference—and essential to running a global company. Life360 CEO Lauren Antonoff takes a different approach.

Rather than adhering to a tightly scripted daily schedule, Antonoff’s workdays are best described as “organic”—shaped less by the clock than by the flow of her month.

“I really think about my routine less in terms of what the morning tonight is, and really what the rhythm is over the course of a month,” she told Fortune.

On a typical day, that means starting work around 8:30 a.m.—a leisurely pace by some CEO standards. From there, her schedule is dictated largely by her first meeting of the day.

“Every day for me is very different,” she said. “I have probably a lot of meetings, but I try to also get time to read and reflect and communicate with people on my team.”
