The ONE Thing: The Surprisingly Simple Truth Behind Extraordinary Results

by Gary Keller and Jay Papasan

This book explains why narrowing your focus to a single priority produces better results than juggling many goals, and dismantles common myths about willpower, balance, and multitasking. In this game world you practice asking the Focusing Question, time blocking your most important work, and building the habits that protect your ONE Thing.

How the book becomes practice

Reading puts ideas in. Retrieval keeps them there. The game is the retrieval.

Walk the world of the book

27 maps, one per part of the book. Signs along the way hold its key ideas, so the walk itself is a refresher.

Battle the characters

131 characters, each a short quiz on one idea. Answer well and the map opens up; a boss guards the end of each one.

Missed ideas come back

Every question you get wrong is re-asked in rematches and boss fights until you get it right. That is the part that makes it stick.
