168 Hours: You Have More Time Than You Think
Shows how to find the hidden hours in a 168-hour week and spend them on the few things you do best, at work, with family and in free time, by dropping or outsourcing the rest.

Table of Content
1. Introduction
58 sec
If your week feels like a race you keep losing, one survey may surprise you: most Americans sleep about eight hours a night, and parents working full time put in no more than 43 hours a week. In 168 Hours, time management writer Laura Vanderkam uses numbers like these to argue that most of us are not short of time. We are short of control over it.
A week holds 168 hours. Once you know where they go, Vanderkam says, you can spend them on the few things you do well and love, and shrink or hand off almost everything else. She proves it with a construction company owner raising six children, a biologist who walks out of pointless meetings and a software developer who hired a cook to win back his guitar practice.
What follows is a way to audit your week, a test for finding your strengths, and practical moves for work, parenting, chores and free time.
2. Find the hours your week is already hiding
1 min 42 sec
A mother of six who runs a growing company still coaches soccer, rides trails and sleeps seven hours. Her edge is not extra energy, and a simple survey suggests you may have more room than you think.
3. Name the few things you do best
1 min 40 sec
A woman who joined a fitness class to lose weight ended up quitting her job to open a studio. Her path shows how to spot the handful of skills that should shape every hour you spend.
4. Choose work that energizes the rest of your life
1 min 42 sec
Plenty of people dream of working four hours a week. A marine biologist who was thrilled at 62 to live underwater suggests a different goal, and a clue to it may sit in your childhood.
5. Take back your work calendar and become time-rich
1 min 45 sec
A biologist finished her PhD without the usual 80-hour weeks while raising a baby. Part of her method would make most employees nervous, and it starts with knowing which meetings to leave.
6. Earn a breakthrough with numbers and a story
1 min 44 sec
A writer landed a book contract within a month of her agent’s pitch. The speed was an illusion, and what lay behind it is a pattern anyone chasing a promotion or a first big break can copy.
7. More time with your kids, less at the stove
2 min 07 sec
Parents spend far less time with young children than they imagine, and much of it goes to tasks that do little for the bond. A developer’s cheap personal chef shows one way to shift the balance.
8. Plan your free time before the TV claims it
1 min 34 sec
Most people insist they have almost no leisure. The averages say otherwise, and they also reveal exactly where those missing hours go each evening, and how to get them back for something you love.
9. Conclusion
1 min 06 sec
What 168 Hours adds up to is a change of question. Too busy is a feeling; whether something is a priority is a choice you can make dozens of times a week. Daytner’s company and six children, Fassbinder-Orth’s exits from useless meetings and Savara’s hired cook all point the same way. Each person decided what their hours were for, then let the rest go.
For working parents, the book’s most concrete suggestion is a mini night shift. Block 5 to 8 p.m. on weeknights as protected family time while the children are awake, and make up the shorter office day by working from 8 to 10 p.m. a few nights a week. Those late hours would otherwise tend to drift toward the television anyway.
The simplest first step is the time log. Keep it honestly for two weeks, lay it beside your list of 100 dreams, and see which hours serve neither. Those are yours to reclaim. Every week brings the same 168 hours, and most of us have been spending them without looking.
About this book
What is this book about?
Many people feel squeezed between long workdays, family demands and endless chores, with nothing left for exercise, hobbies or real time with the people they love. Laura Vanderkam argues that this feeling rarely matches the numbers. A week holds 168 hours, and survey data suggest most of us have far more of them free than we think. Her answer is to take ownership of those hours. She asks readers to log their time, to identify two or three core competencies (the things they do well, love and can apply across their lives) and to judge every activity against them. Through people like a construction boss raising six children, a biologist who leaves irrelevant meetings and a developer who hired a cook to buy back his evenings, she shows the idea at work. Readers get concrete tools: a weekly time log, a list of 100 dreams, a five-year planning method, ways to outsource chores, and a plan for leisure that keeps evenings from disappearing into television.

I loved the practical strategies in this book! The idea that we have plenty of time if we actually count the hours is a total game-changer. Most books just tell you to 'work harder,' but this one actually shows you where the leaks are in your bucket. The case studies were particularly enlightening for me because they showed real-world examples of people balancing high-level careers with family. I felt empowered to take control of my calendar instead of letting my calendar control me. Yes, some of the suggestions are a bit bold—like skipping meetings or ignoring certain chores—but the mindset shift is what matters. It's about being the architect of your own life. Highly recommend for anyone feeling overwhelmed by their to-do list.
Show moreTruly inspiring. I’ve read a lot of productivity books, but this one actually made me change my daily behavior. I stopped saying 'I don't have time to read' and started looking for where my 168 hours were actually going. It turns out I had plenty of time; I was just spending it on things that didn't align with my core goals. The focus on 'core competencies' helped me realize that I was sweating the small stuff at work and at home. I started delegating more and focusing on the projects that actually move the needle for my career. Vanderkam’s voice is clear and motivating, and the case studies provide a great roadmap. It’s not just about doing more; it’s about doing what matters most to you. This is a must-read.
Show moreA fantastic, easy-to-read guide for anyone feeling stretched thin. I personally loved the data-driven approach. Vanderkam uses actual time-use diaries to prove that we have more leisure time than we think, which was a huge wake-up call for me. I’ve already started implementing the weekly planning sessions she recommends, and I feel much more in control of my schedule. While some people might find the 'outsourcing' advice elitist, I saw it more as a challenge to value my own time more highly. Even if you can’t hire a full-time nanny, you can find small ways to simplify your life and reclaim your weekend. It's a very practical book with strategies that you can start using immediately.
Show moreHonestly, this book changed how I view my Monday through Friday. I used to constantly complain that I 'didn't have time' for the gym, but Vanderkam points out that we all have the same 168 hours to work with. It’s a bit of a reality check that can feel a little harsh at times, but I think I needed that kick in the pants. Tracking my time in 15-minute increments was eye-opening, even if it was tedious to actually log everything. I realized I was losing hours to mindless scrolling that could have been spent on my actual hobbies. However, I did find some of the advice about outsourcing tasks a little out of reach for my current budget. Not all of us can just hire a housekeeper to solve our problems! Still, the core message about being mindful of your choices is incredibly powerful if you can get past the somewhat elitist tone.
Show moreVanderkam’s approach is definitely more business-oriented than your typical self-help book. Using the 'core competency' metaphor was an interesting way to look at personal life, though I understand why it might rub some people the wrong way since people aren't corporations. It challenges you to look at your life as a portfolio of responsibilities. I appreciated the emphasis on finding a 'dream job' rather than just settling for a mediocre 9-to-5. While some of the case studies felt a bit 'superhuman,' they did inspire me to stop making excuses about my schedule. There is a lot of focus on parenting, which might not apply to everyone, but the general principles of time-tracking are solid. It's an easy read and definitely worth the money if you're looking for a productivity kickstart.
Show moreThis is an excellent resource if you're willing to be brutally honest with yourself. Vanderkam doesn't pull any punches when she tells you that you probably aren't as busy as you claim to be. It’s a bit of a 'tough love' approach to time management that I found quite refreshing. I especially liked the sections on finding small pockets of time for things that actually matter. My only real gripe is that it ignores energy levels entirely. Not every hour of those 168 is created equal, and I personally can't do high-level creative work at 9 PM even if the slot is open. But as a framework for planning your week, the 168-hour grid is superior to the standard daily to-do list. It’s definitely enlightened my perspective on weekly planning.
Show moreThere’s some good stuff here, but you have to sift through a lot of elitist fluff to find it. I liked the 'Big Rocks' philosophy mentioned in the beginning, even if the author tries to rename it to something more corporate. The 168-hour concept is a great way to zoom out and see the bigger picture of your life rather than just surviving day-to-day. However, I found myself rolling my eyes at the suggestion that knitting or watching a bit of TV is a 'cliché' waste of time. Everyone needs downtime to recharge! The writing style is easy to follow, but it occasionally dips into a condescending vibe that made me want to put the book down. It’s a mixed bag—take the time-tracking tools and leave the lifestyle judgments behind.
Show moreThe premise is solid, but the execution felt a bit out of touch with reality for the average person working a normal job. I appreciated the encouragement to find a 'dream job,' but it felt a bit simplistic and naive. Not everyone can just pivot their career in their 40s because they realized their current role isn't a 'core competency.' I also felt like the author’s own religious views colored the advice a bit too much, which felt out of place in a secular productivity book. That said, the actual time-log exercise was incredibly useful for me. It helped me identify that I was spending way too much time on emails that didn't matter. It’s a decent book, but I’d recommend taking the advice with a grain of salt.
Show moreI really wanted to like this, but the tone was just too judgmental and 'shame-y' for me. The author basically implies that if you aren't spending every second on a 'core competency,' you’re failing at life. As a parent, I found her take on 'quality time' versus 'quantity time' to be really cold and unrealistic. She suggests that hanging out with your kids is a waste unless it’s a planned, 'enriching' activity. Honestly, some of the best moments with my children happen during the 'boring' stuff like doing laundry or chores together. Also, the suggestion to eat pre-packaged meals just to save twenty minutes seemed really depressing and unhealthy. It felt very focused on professional success at the expense of a well-rounded, peaceful home life. It’s just not for me.
Show moreWhat a frustrating and wasteful read. I pick up a book on time management hoping for tips on efficiency or focus, and instead, I’m told to just 'outsource' my entire life to flunkies. The author suggests paying people to do your laundry, your cleaning, and even your grocery shopping as if money grows on trees. This assumes a level of class privilege that the average person simply doesn’t have. It felt less like a guide for the modern worker and more like a manifesto for the wealthy elite. I personally find joy in cooking and being present for my family, so being told those things are a 'waste of time' was actually quite insulting. If you have a personal assistant and a six-figure disposable income, you might like this. For everyone else, it’s just a reminder of what we can’t afford. I want my hours back.
Show moreQuestions about this book
What is the main idea of 168 Hours by Laura Vanderkam?
Vanderkam argues that most people are not too busy but simply not in control of their time. A week has 168 hours, and survey data show many of them are free. By logging how you spend them, naming your two or three core competencies and judging every activity against them, you can drop or outsource the rest and make room for work, family and leisure that matter.
How do you find your core competencies in 168 Hours?
Vanderkam recommends making a list of 100 things you hope to do in your lifetime, covering skills, travel, experiences, milestones and dreams you have already achieved. Do the easy items soon and notice which ones you enjoyed. A core competency is meaningful to you, applies across many areas of your life and is something you do better than most. Being a nurturing person can count.
How does 168 Hours suggest keeping a time log?
Draw a grid with seven columns, one for each day, and a box for every hour. For two to three weeks, write down what you actually do in each hour. The log gives an accurate picture of where your week goes, and later helps you spot the household tasks and TV hours that crowd out what you value.
What does 168 Hours say about outsourcing chores?
Vanderkam argues that housework is rarely anyone’s core competency. Software developer Sid Savara hired a personal chef for $60 a week plus groceries, saved nearly ten hours weekly and even spent less on his credit card. Readers can try meal delivery, or, if that is beyond the budget, online grocery shopping with lists of staples, along with caring less about a spotless house.
Who should read 168 Hours?
It suits working parents, busy professionals and anyone who feels there is no time left for exercise, hobbies or family. Its tools are concrete: a weekly time log, a list of 100 dreams, Sunday planning sessions, outsourcing chores and blocking leisure time before the television can claim it.
