Ultraproductive: The 90-Minute Method to Optimize Focus, Sleep, and Stress

By Eric Partaker and Dr. Christian Poensgen

A revolutionary approach to work and life based on the innovative 90-90-90 method that will boost productivity and transform your everyday routine.

Thriving in today's overstimulated world has never been harder. We treat ourselves like machines--constantly "on," multitasking, and never truly unplugging. But this relentless hustle is backfiring: our current idea of productivity is actually 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, authors Eric Partaker and Dr. Christian Poensgen
reveal the transformative power of the 90-90-90 method--a simple but revolutionary approach that addresses three key aspects of productivity and well-being:

Focus: Dedicate just 90 minutes a day to deep, uninterrupted work--and watch your productivity double.

Sleep: Prioritize 90 minutes of deep sleep nightly to supercharge your brain, increasing output by 2.5 times.

Stress: Break stress cycles every 90 minutes to maintain energy and double your effectiveness.

Drawing from cutting-edge research and their combined expertise in psychology and business, Poengesen and Parataker present a practical framework for becoming ultraproductive--not just surviving but truly thriving at work and at home.

Packed with actionable strategies, relatable examples, and fresh insights, Ultraproductive is the essential guide for anyone seeking focus, and fulfillment in an increasingly hectic world.
