'He walks the talk'

Mark wants to test and live every aspect of focus himself. That’s why each year he explores and experiences a new aspect of focus firsthand. Below are three highlights from that journey:

Mark trained with the Dutch Navy SEALs to explore how you maintain focus when pushed to your physical and mental limits for 72 hours straight. During this “Hell Week,” Mark slept just one hour over three days.

He also climbed the Mont Blanc (15,781 feet) with no prior mountaineering experience, following eight months of focused preparation to understand long-term focus, and resilience under pressure.

And he experienced focus at terminal velocity. Mark took up skydiving to understand how focus holds up while falling at 125 miles per hour. An interesting fact: during his very first solo jump, his parachute malfunctioned.
