The 90-minute method for more focus, better sleep, and less stress
Thriving in today’s overstimulated world has never been harder. We treat ourselves like machines, constantly “on,” multitasking, and never truly unplugging. Yet, this is making us less effective and more exhausted.
But what if the secret to multiplying your productivity by up to 10x lies not in doing more, but in simply doing three things differently?
In Ultraproductive, we reveal the transformative power of the 90-minute method—a simple, science-backed approach that addresses three key aspects of productivity and well-being.
What’s Inside the Book
Learn why the secret to achieving more and stressing less isn’t about doing more, but in optimizing three things: focus, sleep, and stress.
Focus: Dedicate just 90 minutes a day to deep, uninterrupted work and watch your productivity double—without working more.
Sleep: Prioritize 90 minutes of deep and REM sleep nightly to supercharge your brain and increase output by up to 2.5 times—without sleeping longer.
Stress: Break stress cycles every 90 minutes to maintain energy and sustainably double your effectiveness—without burning out.
Beat pseudoproductivity and develop an Ultraproductive Work Ethic, Rest Ethic, and Stress Ethic—even on a busy schedule.
Put it all into practice to multiply your productivity by up to 10x and thrive at work and at home.
What Others Say
Ultraproductive is a refreshingly practical and deeply human guide to doing your best work without the exhaustion.
