Nate’s Notes 268: Sabbaticals—Especially for Non-Academics—as Regret Insurance | Harvard Lecturer DJ DiDonna

Sometimes we need to zoom out before we can know whether we should keep going. DJ had his  dream job, but over time, it stopped being fulfilling. So he took a sabbatical.

And sabbaticals are different from vacations. On vacation, the work is often still waiting, and part of our brain is still running in the background. But on a true sabbatical, we step far enough away from normal life to see more clearly and focus on what is important, not just what is urgent.

Sabbaticals also give us room to experiment with different versions of ourselves. When we’re younger, we have socially acceptable ways to do that — school, internships, missions, study abroad, gap years. But as adults, those opportunities become less common, and we often stop experimenting altogether. We get on a track, stay in the lane, and assume the next thing should look a lot like the last thing. The sabbatical helps us break out.

Finally, I love DJ’s phrase that sabbaticals are “regret insurance.” Maybe we can’t take a sabbatical tomorrow. But what are we doing five years from now? What would we regret never having done? And what would it look like to start planning now?

In short, I hope we can all start planning our next sabbatical.

It’s simple. Please take it seriously.
