The simple and proven 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. 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-minute method—a simple, science-backed 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—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.
Drawing from cutting-edge research and their combined expertise in neuroscience, psychology, and business, Partaker and Dr. Poensgen present an easy-to-understand 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.
