I'm the CEO of Siemens. I reply to most emails with 2-letter responses and don't have recurring meetings — here's a day in my life.

Roland Busch, the 61-year-old CEO of Siemens AG, shares his daily routine. Born in Germany, Busch has spent 32 years at the company, rising from a project head in corporate research and development to his current position as CEO. He oversees a global technology company that focuses on industrial automation, smart infrastructure, mobility, and healthcare, employing over 300,000 people worldwide. Business Insider's Power Hours series offers a glimpse into how top leaders structure their workdays.

Busch begins his day at 6 a.m., hitting the gym for a 75 to 90-minute workout, consisting mainly of weightlifting, HIIT, boxing, and jump rope. By 8 a.m., he either has a breakfast meeting or a quick breakfast in his office while catching up on emails and press clippings. He aims to keep his inbox below 100 emails, responding with short replies like "OK" or "No."

Busch's approach to leadership is influenced by his background in theoretical physics, teaching him to de-layer problems and make decisions with incomplete information. He eliminates recurring meetings with direct reports, preferring them to come to him when needed. During the afternoons, meetings are frequent, and he maintains a paperless desk using specialized software. His assistant, Gundula, manages his schedule, and Busch stays well-traveled, covering about 477,710 miles annually.

Despite his busy schedule, Busch tries to disconnect in the evenings, enjoying dinner meetings with clients, partners, and his team. On weekends, he reconnects with friends and family, playing golf and attending holiday trips together. Occasionally, he picks up the guitar, finding solace in the focus required for playing music.
