Anyone can be sharp when the building is on fire — threat makes the decisions for you, and it feels like clarity. The problem shows up when nothing is burning and you still cannot work.

That is not a character flaw. It is a system calibrated to emergencies that now needs one in order to function. Checking email at red lights. Rereading messages you already answered. Excellent in a crisis, useless on a quiet Tuesday. Exhaustion, renamed drive.

A company running on its founder's arousal level has a single point of failure, and that failure walks around in a body.

About the author

Seçil Sayhan is the founder of MARSA. She spent a decade on one question: what makes a person thrive, instead of just keeping going. Her research tested the obvious answers — nutrition, supplements, physical health — and none of them predicted it; what predicted it was how someone read their own life. Then she built a company of her own and met the same problem from the inside, which is why MARSA has two halves: machines that take the work which repeats, and the training for the person those hours come back to.
