The best motivational quotes from ‘When Breath Becomes Air”
1. You can’t ever reach perfection, but you can believe in an asymptote toward which you are ceaselessly striving.
Kalanithi, a man of science and spirit, saw life as a curve that never quite touches the top—but that’s the point. Strength isn’t nailing perfection; it’s in the endless climb. Whether you’re sketching a dream in Manchester or chasing a deadline in Chicago, this quote whispers: keep going. The effort itself shapes you into something remarkable, even if the summit stays just out of reach.

2. Even if I’m dying, until I actually die, I am still living.
This hits like a thunderclap. Facing death, Kalanithi refused to let it define him—he claimed every heartbeat instead. It’s a raw, stubborn kind of strength, perfect for anyone staring down their own battles. Picture it: a rainy day in London, you’re feeling stuck, then this lands. It’s not denial—it’s defiance, a reminder to live loud until the very last second.
3. I can’t go on. I’ll go on.
Lifted from Samuel Beckett, this became Kalanithi’s quiet anthem. It’s the sound of humanity at its breaking point, yet somehow unbroken. Strength here is messy—it’s tears on the page, a clenched fist, then a step forward anyway. For quote lovers across the Atlantic, it’s a gritty truth: you’re tougher than you think, even when you’re sure you’re done.
4. The fact of death is unsettling. Yet there is no other way to live.
Kalanithi didn’t sugarcoat it—death looms for us all. But instead of crumbling, he leaned into it, finding power in acceptance. This quote is a gut-check: strength isn’t avoiding the inevitable; it’s living fully because of it. Whether you’re sipping coffee in Seattle or tea in Edinburgh, it’s a call to stop running and start embracing the ride.
5. There is a moment, a cusp, when the sum of gathered experience is worn down by the details of living. We are never so wise as when we live in this moment.
Life’s chaos can drown out the big picture, but Kalanithi urges us to pause. Strength lies in that fleeting now—when you ditch the regrets and what-ifs to just be. Imagine standing on a windy cliff in Cornwall or a bustling New York street: this quote pulls you into the present, where real wisdom—and real power—waits.

6. Lucy and I both felt that life wasn’t about avoiding suffering.
Kalanithi and his wife, Lucy, chose to face pain head-on, not sidestep it. It’s a radical kind of strength—less about shielding yourself and more about growing through the bruises. For anyone in the US or UK wrestling with tough times, this is your nudge: suffering isn’t failure; it’s the forge where resilience is hammered out.
7. The physician’s duty is not to stave off death or return patients to their old lives, but to take into our arms a patient and family whose lives have disintegrated and work until they can stand back up.
As a doctor, Kalanithi knew healing wasn’t always curing—it was lifting others when they couldn’t lift themselves. This quote redefines strength as communal, a shared burden that lightens with every hand extended. It’s for the carers, the friends, the quiet heroes in Bristol or Boston who hold the line for someone else.
8. Human knowledge is never contained in one person. It grows from the relationships we create between each other and the world.
Alone, we’re sparks; together, we’re a blaze. Kalanithi saw strength in connection—ideas, love, and growth all bloom from what we build with others. For quote fans, this is a gentle prod: reach out, share, lean in. Whether it’s a mate in Leeds or a stranger online, your strength doubles in the exchange.
9. Will having a newborn distract from the time we have together? ‘Wouldn’t it be great if it did?’ I said.
Facing his end, Kalanithi and Lucy chose to bring life into it—a daughter, Cady. This quote is strength dressed in joy, picking love over fear when time’s running short. It’s a beautiful gut-punch: don’t shrink from what matters, even when it’s hard. For readers anywhere, it’s a dare to embrace the messy, glorious now.
10. Be ready. Be seated. See what courage sounds like.
This feels like Kalanithi’s final charge—a call to sit still and listen as bravery roars through. Strength isn’t always loud action; sometimes it’s quiet, steady presence. Picture it echoing in a hushed café in Oxford or a subway in LA—it’s an invitation to tune in, to feel courage ripple through you like a drumbeat.
