Jedna rzecz. Zaskakujący mechanizm niezwykłych osiągnięć

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.
