Matt Haig’s novel The Midnight Library asks: What if you could explore every what-if of your life, specifically those that turned into regrets? How many of your other lives would actually turn out better than your real one?

It’s an intriguing philosophical question that quickly turns personal for the book’s protagonist, Nora Seed, who comes to learn that each book in the titular library—rendered as a kind of metaphysical manifestation of purgatory—represents one of the infinite versions of her life.

Adventures in space-time

The idea of exploring what-ifs through magical realism or sci-fi isn’t new. It’s the narrative foundation of some of my favorite films (It’s A Wonderful Life, Back to the Future trilogy) and other intriguing cinematic counterfactuals (The Man in the High Castle, The Last Temptation of Christ, About Time).

But rather than focusing on (as Doc Brown would call it) one specific temporal junction point in the entire space-time continuum—what if George Bailey had never lived, what if Biff stole the Almanac, what if the Nazis won—The Midnight Library extends its ambit to the many sliding-doors moments in a single life.

Nora is given countless opportunities to choose and experience parallel lives where none of her regrets came to pass. “I stayed with that ex-boyfriend” and “I didn’t give up swimming” and “I pursued my dream of becoming a glaciologist” all get a spin. But none of these supposedly ideal realities live up to her expectations.

While she’s able to shorten her list of regrets—an immensely valuable gift in itself—her pursuit of happiness doesn’t solve the deeper existential crisis that plagues all of us at some point: per Mary Oliver, what will you do with your one wild and precious life?

4,000 Weeks

That question infuses another of my recent reads: Four Thousand Weeks: Time Management for Mortals by Oliver Burkeman, an approachably philosophical exploration of the wily, incorrigible thing called time and our dysfunctional relationship with it.

I have an extensive list of quotes from the book that make for good ponderin’, but there are three specific ones that would fit right into The Midnight Library. (Synchroncity knows no bounds, temporal or otherwise.)

First, a reality check:

The world has an effectively infinite number of experiences to offer, so getting a handful of them under your belt brings you no closer to a sense of having feasted on life’s possibilities.

Therefore, Burkeman writes, you have to make choices:

Once you truly understand that you’re guaranteed to miss out on almost every experience the world has to offer, the fact that there are so many you still haven’t experienced stops feeling like a problem. Instead, you get to focus on fully enjoying the tiny slice of experiences you actually do have time for—and the freer you are to choose, in each moment, what counts the most.

And once you do that:

If you can hold your attention, however briefly or occasionally, on the sheer astonishingness of being, and on what a small amount of that being you get—you may experience a palpable shift in how it feels to be here, right now, alive in the flow of time.

That “astonishingness” of being alive in the flow of time doesn’t arrive on command. You have to reorient your mind and your attention to create the conditions that allow for it to reveal itself.

In The Midnight Library, that process looks like an anguished young woman replacing her perceived unworthiness with gratitude for mere existence. (Just like George Bailey.)

In Four Thousand Weeks, that looks like embracing temporal limitations rather than resenting them.

And in my life, that looks like treating the things I love—my wife and son and family and friends and typewriter collection and bike rides and movie nights and library books—as the temporary gifts they are, for however long I live.
