The book in one sentence
Big Time Off argues that a planned sabbatical helps people stay present for life's key moments and can reshape identity, relationships, creativity and career direction.
About the author and the book
DJ DiDonna is a senior lecturer at Harvard Business School and the founder of the Sabbatical Project. The book was published by Simon Element, an imprint of Simon & Schuster, on July 21, 2026. Retailers list the hardcover at between 288 and 320 pages. The book draws on original research and stories from teachers, nonprofit leaders, startup founders and Fortune 500 employees. Arthur C. Brooks endorses it. This label is a loose fit, since the book concerns work rhythms and time more than daily habits.

5 ideas worth remembering
1. Do not sleepwalk through life
DiDonna argues that a sabbatical helps people stay present for celebrations, hardships and transitions, instead of drifting past them.
2. A sabbatical is not a vacation
Time off with purpose can help you chart a new career path, reconnect with your humanity and live more authentically.
3. Choose your timing
Taking a break proactively gives you control, whereas waiting for burnout or a layoff may force a worse version.
4. Use an archetype
The explorer, the seeker and the achiever give shape to the time away and help you avoid typical pitfalls.
5. Make leave workable
The book offers best practices for individuals and for organisations that want extended leave to be sustainable.
Why DiDonna argues for stepping away
DiDonna's argument starts from a simple observation: many people move through their working lives without ever stopping, and then discover that they have been sleepwalking. A sabbatical, in his view, is a deliberate way to stay present for life's celebrations, difficulties and transitions instead of drifting past them.
He writes with some authority. DiDonna is the founder of the Sabbatical Project and a senior lecturer at Harvard Business School. The book combines original research with stories from teachers, nonprofit leaders, startup founders and employees of Fortune 500 companies, which gives the argument a range beyond the usual tech-worker anecdote.
The framing is also worth noting. This is not a book about escaping work or about a luxury holiday. It treats extended time away as a tool for reshaping identity, relationships, creativity and direction, and it asks the reader to think about when and how to use it.
Sabbatical versus vacation, and the question of timing
A key claim is that sabbaticals differ from vacations. A vacation recovers energy; a sabbatical can help you chart a new career path, reconnect with your humanity and live more authentically. The distinction matters because it changes what you plan for. A vacation can be filled with rest, while a sabbatical asks for intention.
Timing is the second major point. DiDonna argues that people should take a sabbatical proactively, so that a crisis does not force the decision. Burnout, illness, layoffs and family emergencies often create unplanned breaks. A chosen break, he suggests, is likely to be more useful than one imposed by events.
The book also offers three archetypes for navigating the time: the explorer, the seeker and the achiever. Each archetype comes with its own pitfalls, which the book describes so that readers can avoid them. The purpose is practical. Many people who take time off feel lost after a few weeks, and a simple model of what you are trying to do can help.
Making it workable, and where the argument stops
Another strength of the book is that it does not stop at the individual. It offers practices for organisations of all sizes that want extended leave to be workable and sustainable. That is a useful addition, because the usual obstacle to a sabbatical is not desire but logistics: who covers the work, how the return is managed and how the company supports the person.
This focus gives the book some relevance for managers and human resources teams. It also answers the common objection that sabbaticals are only for the privileged, at least in part, by discussing how to make them feasible in different circumstances.
The limits are real. Extended time off requires money, flexibility and often employer goodwill, which many workers do not have. The book is an argument for a practice that not everyone can adopt, and readers should weigh its advice against their own financial and family situation. It is also a recent release, so independent critical assessment is still limited.
