Timeboxing: The Power of Doing One Thing at a Time
Marc Zao-Sanders
About the book
Marc Zao-Sanders, co-founder and CEO of Filtered and the author of several influential Harvard Business Review pieces on productivity, uses this book to develop the technique of timeboxing — planning your day by reserving a specific block of calendar time for every task in advance. Drawing on his own research and the habits of highly effective people, he argues that this deceptively simple technique significantly reduces procrastination, multitasking, and overload, because it forces us to decide on priorities in advance rather than reacting to demands as the day unfolds. The book offers concrete steps for adopting timeboxing in daily work, along with answers to common obstacles such as unpredictable interruptions and estimating how long tasks will take. Published in 2025, it quickly drew attention as one of the most practical guides to time management in today’s digitally overloaded work environment.
