What If Nothing Was Wasted?

A quiet reflection on the paths we once wished to rewrite – and the strength they quietly built.

If you could travel back in time and give your younger self one piece of advice, would you do it?

The idea sounds comforting. Correct the wrong. Avoid the wrong turn. Save yourself from unnecessary pain, but there is a problem with this thought experiment.

In the film Back to the Future, the protagonist accidentally interferes with the moment his parents first fall in love. As the timeline shifts, something unexpectedly strange begins to happen, his photograph slowly begins to erase him from existence. To survive, he must ensure that his parents fall in love exactly as they originally did and get married so that he can continue to exist.

Not slightly differently. Not approximately. Exactly.

Because even the smallest change in the past might erase the future version of himself entirely. It raises an unsettling question.

If we could truly rewrite parts of our past, would we still become the person we are today?

There is another moment in the film that captures this idea in a different way.

At one point, Marty attempts to warn Doc Brown about his eventual demise decades in the future. Doc refuses to listen to the message and explains why.

“Having information about the future can be extremely dangerous. Even with the best intentions, it can backfire drastically. I will discover what lies ahead through the course of time.”

It is a simple line, but it carries a surprisingly thoughtful idea.

Whether we try to rewrite the past, or control the future, our urge to ‘change the inevitable’ often assumes we fully understand the consequences. More often than not, we do not.

There is something deeply human about our desire to correct time.

We replay conversations in our minds.
We imagine alternative paths.
We quietly construct better versions of the past where we made wiser choices, spoke the right words, or avoided unnecessary detours.

Yet time itself moves only in one direction. Perhaps this is not a flaw in the design of life, but its quiet wisdom. If every mistake could be revised and every wrong turn corrected, experience itself would lose its power to shape us.

Many reflective prompts ask the same familiar question:

What advice would you give to your younger self?

It is a comforting exercise. But lately, I have begun to wonder if the question itself is slightly misplaced. Because to answer it honestly, we must first assume that something in the past was meant to be ‘corrected’.

And I am no longer entirely sure that is true. Like many people, I have had periods in life that I would not willingly relive. There were times of doubt, heaviness, and quiet internal struggle that the outside world rarely sees.

At the time, it simply felt like something to endure.
Something to get through.
Something to move beyond.

But having walked through and out of those darker stretches, I began to notice something unexpected. What once felt like a social stigma…
was also a deep journey inward.

Not comfortable. Not glamorous. But undeniably formative.

It forced questions I might never have asked otherwise.
It slowed me down when I would have rushed.
It revealed parts of myself that only difficulty seems capable of uncovering.

We often fall back on familiar phrases:

Accept yourself. Do not regret the past. Everything happens for a reason. There is truth in these ideas. But repeated often enough, they can start to sound like cliché rather than self-reflections.

Perhaps a more honest way to look at the question is this.

When we ask, “What advice would you give to your younger self?”, we are often looking backward with the quiet confidence of hindsight.

We see the mistakes. We see the detours. We see the unnecessary pain.

What we do not see as clearly is what those moments were building blocks of life experiences inside us. I was reminded of this recently when I looked back at my dissertation from 2020. At the time, writing it felt overwhelming.

Messy. Mentally exhausting. Filled with moments of quiet doubt.

There were days when I wondered if I could actually finish it. And yet, looking back today, I sometimes pause and think: ‘I really wrote that’.

Not because it was perfect, but because I now understand what it took internally to complete it.

The discipline. The uncertainty. The persistence that did not feel heroic at the time. No piece of advice given earlier could have replaced the experience of walking through it.

Perhaps the question was never meant to be:

What should I have done differently?

Perhaps the more revealing question is:

What did I survive that quietly built me?

Because when we frame the past only as a collection of mistakes to correct, we overlook something important.

Endurance leaves structure. Struggle leaves insight. Even the seasons we would never volunteer to repeat often carry the blueprint of who we later become. So these days, when I encounter the familiar prompt:

‘What would you tell your younger self?‘

My answer has grown quieter. Less corrective. Less urgent. More appreciative.

Not everything in the past needs editing.

Some parts simply needed to be lived.

A letter to my younger self?

No, thank you.

The journey already wrote it through the course of time.
