A única coisa: A verdade surpreendentemente simples por trás de resultados extraordinários

The idea of narrowing down to a single thing feels powerful but also challenging. I'm curious what inspired this approach and how it evolved during writing.

Applying this principle sounds straightforward, but in real life, priorities often clash. Has anyone experienced breakthroughs or setbacks when trying to focus on just one goal?

The book offers various tips, but I'd love to hear which ones actually made a difference in daily routines or work habits for others.
