I Don't Have Time: Five Hours a Week
About this audiobook
How many times have you said it this month? I don't have time.
Nobody argues with it. Tell someone you're afraid and they reassure you. Tell them you don't know how and they send you a course. Tell them you don't have time, and they nod, and the conversation ends right there. This book deliberately starts it.
The day is exactly as long for you as for anyone else. The free part of it is not. "I don't have time" hides two claims that sound exactly alike. One is about capacity: other people have first call on your week. The other is about priority: your week is already committed to things you have decided matter more. This book shows you which one is yours, using documents rather than feelings, and takes the answer seriously either way.
Five hours a week at most, and less if your life can't spare five. Thirteen weeks. Pieces as small as fifteen minutes. One exercise per chapter, each one finishable in a single sitting, and none of them needs a free evening, a new app or a quiet weekend.
Inside:
The 168 subtraction: every hour in a week, minus only what a payslip, a timetable or an alarm can proveWho the average hides: parents of small children, 38.2 million Americans caring for an older person, 8.8 million holding two or more jobsHow being busy became a status symbol, and a fifteen-minute exercise that turns "I don't have time" into "it's not my priority", said out loudThe mere urgency effect: why the task with a clock attached beats the one that matters, re-tested in 2026 with 2,374 new participantsEinstein, Bergson and the difference between the hour on a clock and the hour you actually live throughThe famous 23 minutes after an interruption, what it really measured, and the note that makes fifteen-minute pieces add upA time cap with a decision point, and what the man who built Gmail says about twenty percent timeA chapter for readers whose hours genuinely belong to other people: 16.4 billion hours of unpaid care every day, and a famous study of scarcity that failed when others repeated itWhy the calm you keep waiting for never comes, and the fresh starts your calendar already holdsWhy giving time away can make you feel you have more of it, and how twenty minutes of help becomes your first researchThe waiting you already do: 26.8 minutes each way to work, 121 minutes for one medical visitThe empty-slot test, for when it isn't the clock at allEvery chapter names its studies, authors and years. When a finding is weaker than it sounds, the chapter says so, and when the research simply does not exist, it says that too.
Diego Segura is an industrial engineer who has spent his career working out how systems fail and how to fix them. He holds an MBA and a master's in Digital Technology from Boston University, and has worked with Stanford, Harvard, MIT and Boston University. He has spent his working life starting and running companies, most recently a marketing and strategy business that he runs himself. He has also told a former colleague for weeks that he had no time for a two-hour favour, and let one client project take eight hundred to nine hundred hours because he never set a limit. Both stories are in here.
No resignation letter, no five o'clock alarm, no sacrificed sleep. The book ends with one short message to one person, offering them one thing for one price.
It will not make your week any longer, because nothing can. It shows you what your week is actually made of, and helps you give a small, protected part of it to something you have wanted for a long time.
