168 Hours: You Have More Time Than You Think
Laura Vanderkam
Shows how working parents can fit a serious career, family time, a relationship and personal rest into one week by planning ahead, using flexibility and dropping perfectionism at home.

If your week feels like a constant trade between your career and the people you love, Laura Vanderkam has numbers that may surprise you. In I Know How She Does It, she points out that even mothers earning over $100,000 a year, who work up to 44 hours a week, still have 68 hours left after work and sleep. Her book focuses on working mothers, but its lesson fits anyone who feels squeezed: the week is bigger than it feels.
The time is there. What makes the difference is how it gets arranged. The successful women she describes plan their hours ahead, use whatever flexibility their jobs allow, guard the moments that matter most and stop chasing perfection in the ones that don’t. Along the way you will pick up moves to try this week: a split shift, a shorter meeting, a Friday plan, a family breakfast, a lunch date and a vacation day taken before exhaustion forces one.

Working mothers often describe themselves as workaholics with no time left. A national time survey and some simple arithmetic tell a very different story, and point to the real reason the workday feels endless.

Nearly all full-time employees, 97 percent, already have some freedom over when and where they work, and the key is to use that freedom fully. A study of home workers suggests the fear of blurring work and life is overstated.

Leaving the office on time can make you feel efficient or hopelessly behind. The difference comes down to when you tackle certain tasks and how ruthlessly you treat your calendar.

Sitting in the same room as your children is not the same as spending time with them. And the family dinner many parents feel guilty about missing may be the wrong meal to chase.

Vanderkam’s book changes the question a busy parent asks. Instead of what to give up, it asks where the hours actually go, and the arithmetic answers generously: even a 44-hour job leaves 68 hours a week beyond work and sleep. The women she studied fit career, family, partner and self into that space by deciding ahead of time, using every bit of flexibility they had and refusing to let perfectionism eat what they had won.
None of this needs a new job or a new life. Put your hardest task at 8:00 tomorrow and trim one meeting. Write next week’s plan on Friday afternoon. Pick a breakfast, a library trip or a lunch date and treat it like an appointment. Let one chore or one morning argument go, and book a vacation day while you still have energy to enjoy it.
Interruptions will keep coming: snow days, closed kindergartens, airport runs. They make the week feel smaller than it is. The hours are still there, and the people who seem to do it all are mostly the ones who decided in advance what those hours were for.
Many working parents feel forced to choose: give everything to the job and miss the family, or protect home life and let the career slide. Laura Vanderkam argues that this trade is mostly an illusion created by a week that feels smaller than it is. A week has 168 hours, and even a 44-hour job leaves plenty of time outside work once sleep is counted. The book focuses on working mothers, but its methods suit anyone stretched between job and home. Vanderkam shows how to use workplace flexibility through split shifts and remote days, how to protect peak morning energy and cut meetings, and why planning next week on Friday afternoon beats starting from scratch on Monday. She then turns to home: shared activities instead of shared television, family breakfasts instead of rare dinners, lunchtime dates, help with chores and childcare, and real leisure for yourself. Readers get a practical, week-by-week approach to reclaiming hours they already have, supported by figures from time-use surveys, workplace studies and the stories of women who make it work.
Working mothers and fathers who feel they must choose between career and family.
Professionals whose evenings vanish into chores, email and television.
Couples and burned-out employees who want time for each other and for themselves again.

Listeners find this book an accessible read and value its practical, usable guidance, with one listener identifying it as a must-read for mothers in the workforce. This well-researched guide uses engaging stories and thorough time logs to help people carve out space for leisure and fun. Listeners appreciate the distinctive approaches to managing schedules, with one listener highlighting the importance of planning challenging tasks earlier in the day, and value the emphasis on family life and cohesive relationships.
Picked this up during a particularly stressful month, and Vanderkam’s approach to the "168 hours" concept really shifted my mindset. Instead of obsessing over a failing 24-hour cycle, looking at the whole week helped me see where my time actually went. The data from the time logs is fascinating, showing that even high-earning women often have more leisure time than they admit to themselves. Truth is, I started planning my hardest tasks for Monday mornings and suddenly felt way more in control. It's essential reading for any working mother who feels like she's drowning in a sea of 'shoulds.' Even if you don't make six figures, the strategy of finding small pockets of time is incredibly actionable and life-affirming. This isn't just another productivity book; it's a recalibration of how we value our minutes.
Show moreFinally got around to reading this, and even as a stay-at-home homeschooling mom of four, I found so much value in these pages that I didn't expect. You might think a book about six-figure earners wouldn't apply to my life, but the philosophy of evaluating time like a budget is universal and truly refreshing. Vanderkam encourages us to look at our lives as a mosaic, where even small pieces of leisure add up to a beautiful whole rather than a fragmented mess. I've started reclaiming my evenings by realizing that I don't actually have to achieve 'Inbox Zero' or have a spotless house every night to be successful in my role. The stories of these women are inspiring, and the author's tone is refreshing because she refuses to let us play the martyr. It helped me find time for my own hobbies again—something I thought was gone forever—which has made me a much better and more patient mother in the long run. I highly recommend this for anyone feeling lost in the daily grind.
Show moreThe chapter on work really challenged my assumptions about what a productive day actually looks like. Vanderkam suggests that we often inflate our work hours in our minds, and her analysis of 143 time logs backs that up quite convincingly. I’ve started implementing her 'split shift' idea—leaving work on time to see the kids and then doing an hour of emails after they go to bed. It sounds exhausting, but in practice, it’s much better than staying late and missing dinner every night. To be fair, she does assume you have a lot of control over your schedule, which isn't true for everyone. But the emphasis on planning leisure and fun as strictly as we plan meetings is a game-changer for my mental health. This is essential reading for mothers who love their careers but hate the guilt.
Show moreWow. This actually changed how I view my weekends. Vanderkam’s advice to 'plan challenging tasks earlier' helped me stop procrastinating on the big stuff, leaving my Saturdays actually free for the kids. I know some people struggle with her focus on high-earners, but if you look at the core strategies, they are applicable to anyone with a bit of agency over their schedule. The writing style is engaging and the anecdotes are actually relatable, even if the salaries aren't. Gotta say, I'm feeling much less 'harried' and much more 'intentional' since finishing this. It’s a great piece of research for anyone tired of the 'busy' cult. If you need permission to enjoy your life, this is it.
Show moreEver wonder why you feel like you're working 80 hours a week when the clock says something much lower? Vanderkam uses her 'mosaic' method to show how we often buy into a narrative of martyrdom that doesn't match our actual time logs. I loved the focus on energy management over strict hour-by-hour scheduling, especially the tip about front-loading the week with challenging projects. It’s well-researched and filled with interesting anecdotes from women who are actually making high-level careers and big families work together. Not gonna lie, some of the suggestions to just 'exercise during lunch' feel a bit simplistic for certain office environments. However, the core message—that we have more time for fun and family than we think—is a refreshing change from the usual doom-and-gloom parenting books. It’s practical, data-driven, and surprisingly hopeful.
Show moreAs someone who is a father trying to balance a demanding career with being present for my kids, I found these insights surprisingly applicable. The takeaway that we don't need to do something every single day to make it a 'habit' was a huge relief for my exercise routine. Instead of failing at a 5 AM gym session daily, I now look at my 168 hours and slot in a long run on the weekend and a walk during Tuesday's lunch. Vanderkam’s data shows that 'busy' is often a choice or a linguistic habit rather than a mathematical reality. My only gripe is that the book ignores the rigidness of many blue-collar or service jobs where flexibility isn't an option. Still, the focus on family life and building cohesive relationships through intentional planning is top-notch.
Show moreAfter hearing so much buzz about this productivity expert, I finally dove into her data-heavy look at the lives of successful women. The book is definitely easy to read and contains some perfect actionable advice regarding the 'scraps of time' we all waste on our phones. But I couldn't shake the feeling that the book is a bit soulless, focusing so much on the mechanics of time that it misses the emotional weight of being a parent. She claims that if you see your kids for 15 minutes in the morning and put them to bed twice a week, you’re spending 'plenty' of time with them. Frankly, that’s a hard pill to swallow for someone dealing with major mommy guilt. It's a useful resource for logistical planning, but it won't necessarily make you feel better about the choices you're making at work.
Show moreNot what I expected, but I’m glad I finished it for the sake of the different perspective it offers on 'having it all.' The book is basically productivity porn for the corporate elite, but if you can look past the privilege, there are some real gems here. I found the section on energy management much more useful than her actual time management tips, as it acknowledges that we aren't robots. Personally, I found Brigid Schulte’s 'Overwhelmed' to be a much more comprehensive look at why we feel harried, as she digs into the sociology of it all. Vanderkam is more of a 'fix it yourself' person, which is fine, but it can feel a bit dismissive of the genuine burnout people experience. It’s worth a read if you need a kick in the pants to start living, but take the stats with a grain of salt.
Show moreWhile the research on time diaries is definitely unique, I found the inclusion criteria for this study incredibly alienating. Vanderkam only focuses on women making over $100,000, which ignores the reality of the vast majority of working mothers who can't just 'outsource' their way out of a mess. To be fair, some of the advice on batching chores is helpful, but the tone feels like being cornered by a wealthy acquaintance at a country club. She suggests that we work less than we think because we take lunch breaks or doctor appointments, but that feels like a semantic trick to minimize real exhaustion. Look, if you have the resources for a twice-weekly cleaning service and flexible corporate hours, this book is a goldmine. For everyone else, it’s a bit of a slap in the face that ignores the systemic issues keeping women harried.
Show moreThis book made me incredibly frustrated because it feels like a collection of data points designed to gaslight overworked women. Vanderkam argues that we don't actually work 60-hour weeks because we count our vacation days and sick leave in the average, which is just bizarre logic. If I'm at the office until 8 PM four nights a week, I'm working long hours, regardless of whether I took a Friday off three months ago! The author seems to believe that success is only possible through these grueling schedules and that we should just 'make chores fun' to cope. It’s a narrow, boring view of what a successful life looks like, centered entirely around high salaries and professional prestige. I’m honestly surprised this is marketed as a helpful guide, as it mostly just made me feel judged for being tired.
Show moreLaura Vanderkam argues that working mothers have more time than they think. A week has 168 hours, and even a mother working 44 hours who sleeps eight hours a night has 68 hours left. Interruptions make the workday feel longer than it is. With planning, flexibility and less perfectionism, she says, there is room for a career, family, a partner and personal time.
She suggests using workplace flexibility through split shifts or remote days, tackling your hardest task in the morning when energy peaks around 8:00, skipping meetings that do not need you and shortening the rest, and booking an evening activity to leave on time. She also recommends planning the coming week on Friday afternoon to avoid an unproductive Monday.
Vanderkam distinguishes being around your family from being with them. She recommends planning a shared weekday activity, such as a playground visit, a library trip, swimming or a bike ride, rather than watching television together. Since a UCLA study found only 17 percent of families eat dinner together nightly, she suggests family breakfasts or lunches, and occasionally bringing children to work.
The book centers on working mothers and their stories, but its methods apply widely. Anyone who feels torn between job and home can use its ideas: counting the week’s real hours, using flexible schedules, cutting meetings, planning on Friday, scheduling time with a partner, accepting help with chores and taking vacation days before burnout sets in.
She cites Larry Kanarek, the manager of the McKinsey office in Washington, D.C. He observed that everyone leaving because of exhaustion and burnout still had unused vacation time. Vanderkam’s advice is to take days off before you are worn out, because caring for yourself is what lets you keep doing well as a professional, partner and parent.
