I found an old university application form last week, tucked inside a book I hadn’t opened in years. The course I’d nearly applied for: astrophysics. I’d spent an entire summer convinced I’d spend my life studying the stars, only to change my mind at the last moment.
There’s a peculiar grief we rarely name. It lives in the space between who we are and who we might have become: the architect you never trained to be, the musician whose hands never learnt to play, the version of yourself that chose differently at every crossroads.
We carry these phantom selves within us, these unrealised possibilities that haunt the corridors of our minds during quiet moments. They whisper of alternate timelines, of roads not taken, of the courage we didn’t summon or the opportunities we let slip through our fingers.
The existentialists understood this weight. Sartre spoke of the anguish that comes from recognising our radical freedom: that every choice we make simultaneously closes doors we can never reopen. To choose one path is to condemn infinite others to nonexistence.
Sometimes I wonder about that version of me who became an astrophysicist. Would he have been happier? More fulfilled? The truth is, he would have wondered about other paths too. He’d have his own application forms tucked away, his own ghosts of unrealised lives.
But here’s where it gets interesting: these unrealised versions of ourselves aren’t failures. They’re the necessary cost of becoming someone specific. Identity, after all, is as much about what we refuse as what we embrace.
Consider the Japanese concept of ma: the meaningful space between things. Your identity exists not just in who you are, but in the deliberate emptiness where other selves could have been. This negative space gives your actual life its shape, its definition, its meaning.
The mourning of unlived lives can become a trap. We romanticise the hypothetical, forgetting that every version of ourselves (even the ones we never became) would have carried their own regrets, their own unrealised possibilities.
There’s wisdom in acknowledging these ghost selves without being haunted by them. They remind us that we’ve made choices, that we’ve committed to something, that we’ve staked a claim on one particular way of being human.
The question isn’t whether you chose the “right” version of yourself. The question is whether you’re willing to fully inhabit the one you’ve become: to stop hedging your bets on alternative futures and instead invest completely in the present you’ve created.
I put that application form back in the book. Not with regret, but as a reminder that I had enough life to make choices that mattered. The astrophysicsit I never became isn’t an accusation. He’s simply the price I paid to become whoever I am now.
