This excerpt from The ONE Thing argues that extraordinary results stem from focusing on a single, most important task—the ONE Thing—rather than multitasking. The authors support this claim with anecdotes of successful individuals and businesses, illustrating how prioritizing one key activity leads to disproportionate success. They also explore common misconceptions about success, such as the belief in multitasking and the need for a perfectly balanced life, and propose strategies for identifying and pursuing the ONE Thing, including the use of the "Focusing Question" and time blocking. Finally, the authors emphasize the importance of purpose, accountability, and building supportive environments to achieve lasting success.
