Welcome to my standard night at ISB. It’s 4am and it’s both late night and early morning. I can hear the Gurbani playing in the east as Calvin Harris slowly morphs into Nucleya to the west of my room. Outside in the living room, people are discussing public policy in rural India, over a game of Monopoly, and as I look out of my window I see a rabbit hop towards the wood heated from last night’s bonfire. It gets too close and immediately backs away, hopping once again into the darkness. None of us gets a how-to guide, you see? Everybody’s just somewhat winging it.

The wine is over and the temperature is at it’s lowest for the day, so we bring out the rum. The Monopoly has begun to disturb friendships, so we bring out the rum. We’re out of ideas and the paper is due in two hours, so we bring out the rum. A little liquid courage never hurt anyone, so we bring out the rum. Only to wake up the next morning, thirsty, exhausted, drowsy – yet somehow more accomplished, dearer, warmer.

I won’t lie, it’s been an especially gruelling year – but that’s what we came here for in the first place, isn’t it? A year that would ideally have taken two. Not just in what we learn and experience but also physically, mentally, emotionally. Some days we surprise ourselves and own it – the classes, the assignments, the study groups and the networking, still somehow managing to spend quality time with the ones who matter. And yet, some days, we leave our spectacles in the refrigerator.

That’s the beauty of life at this pace. Ever so often it reminds you that you’re still human. Allow yourself a breath – a wasted day, a missed deadline, a failed interview. And then get back up, immediately. That’s what we came here for in the first place, isn’t it?

A year that would ideally have taken more time.

And now with graduation day almost in sight, I try to think of all the ways to tell people all the things I wish I’d known when I began my year here, most of which have to do with emotional stability. That even as you start out, you will meet people who see the same stars as you do. They will inspire you, overwhelm you, bring out the best and worst in you and slowly become a part of you.

But people, as people do, change. Sometimes you just outgrow the ones you started out with, for you mature with experiences, not with years. All of a sudden you’ll be looking at the same stars, seeing different constellations. And nobody is better or worse for it, we just make our own momentum as we go from bone crushing hugs to firm handshakes.

And then there’s the ones you find and keep – different momentums, different starting points and all that jazz. But the same escape velocity. They come out of nowhere and as they do, you realise that for this one year, you’re always one decision away from a parallel universe. And for that one reason, this year is the beginning of anything you want.

I wish we could have bottled this year, like a perfume. Breathed in a little every time life got dreary or uninspiring.

But we can’t, so we bring out the rum.
