I Know How She Does It

I Know How She Does It is a must-read for anyone interested in time management—particularly parents who feel that work and family have consumed every available hour.

Rather than relying only on advice or personal anecdotes, Laura Vanderkam analyses 1,001 days of hour-by-hour time logs from professional women earning at least $100,000 a year. What she finds challenges the familiar image of successful working mothers permanently rushing between meetings, school pick-ups and unfinished household tasks.

One of the book’s most valuable ideas is that we should assess time across a whole week rather than judging our lives by one difficult day. A late meeting on Tuesday does not mean we never see our children. A chaotic morning does not mean the entire week is out of control. When we look at all 168 hours, we often find more flexibility—and more meaningful family time—than we initially imagined.

The book also questions the accuracy of the stories we tell ourselves about time. People frequently work fewer hours than they estimate, while overlooking the short but valuable periods spent connecting with their families, exercising, resting or pursuing something personally meaningful. A few unrushed hours can hold more genuine connection than an entire distracted day.

The sample is undeniably privileged: high earners often have access to flexibility and paid support that many families do not. The book is therefore not a universal formula. Nevertheless, its core method—looking at real time rather than perceived time—is useful for almost anyone.
