Struggles Make Life Strong

Posted on April 3, 2025

Life, in all its complexity and beauty, is a product of struggle. From the earliest stirrings of existence on Earth to the modern human experience, adversity has been a relentless force shaping who we are and what we can become. To understand this, we can begin at the very dawn of life, where even celestial bodies like the Moon played a pivotal role in forging the resilience that defines us.

The Moon and the Birth of Life

Billions of years ago, Earth was a chaotic, molten sphere, devoid of the conditions we now associate with life. Enter the Moon, a cosmic companion born from a cataclysmic collision between Earth and a Mars-sized protoplanet. This violent event, known as the Giant Impact Hypothesis, left behind a debris ring that eventually coalesced into the Moon. While this may seem like a distant astronomical footnote, its consequences were profound for life’s emergence.

The Moon’s gravitational pull stabilized Earth’s axial tilt, preventing wild climatic swings that could have snuffed out nascent life before it had a chance to take hold. More crucially, its tidal forces churned the primordial oceans, creating a dynamic environment where organic molecules could mix, collide, and combine. Scientists believe these tidal zones—where water met land in rhythmic cycles—served as crucibles for the first self-replicating molecules, the precursors to RNA and DNA. Struggle, even at this molecular level, was inherent: only those compounds resilient enough to withstand the relentless ebb and flow of tides survived to pass on their legacy.

This was no gentle process. The early Earth was a harsh proving ground, bombarded by meteorites, scorched by volcanic eruptions, and bathed in ultraviolet radiation. Yet, it was precisely this crucible of struggle that forged life’s tenacity. Single-celled organisms emerged, battling for scarce resources, adapting to toxic conditions, and evolving mechanisms to endure. The Moon, silently tugging at the seas, set the stage for a drama of survival that would unfold over eons.

Biological Struggles and Evolutionary Strength

Fast forward to the Cambrian Explosion, roughly 540 million years ago, when life diversified into an astonishing array of forms. Predation became a driving force: trilobites developed hard exoskeletons to fend off attackers, while early predators evolved sharper senses and faster bodies. Struggle wasn’t an aberration—it was the engine of evolution. Natural selection favored those who could endure, adapt, and overcome, whether through camouflage, speed, or sheer toughness.

Consider the vertebrate lineage that eventually led to us. Fish that ventured into oxygen-poor waters developed rudimentary lungs, a desperate adaptation that paved the way for amphibians. On land, reptiles faced arid deserts and scarce food, evolving efficient metabolisms and protective scales. Mammals, emerging in the shadow of dinosaurs, survived by being small, nocturnal, and resourceful—traits honed by the constant threat of extinction. Each step was a struggle against environmental pressures, predators, or scarcity, and each victory strengthened the lineage.

Humans, too, are children of struggle. Our ancestors, hunched and vulnerable on the African savanna, faced starvation, predators, and brutal climates. Those who survived did so by innovating: crafting tools, mastering fire, and forming cooperative groups. Physical frailty gave way to mental fortitude, and the harshness of existence sculpted our species into problem-solvers. Anthropologists note that the human brain tripled in size over millions of years, a testament to the cognitive demands of survival. Struggle didn’t just make us possible—it made us strong.

The Personal Forge: Struggles in Human Life

Zooming into the individual human experience, this pattern holds. Muscles grow stronger when torn and repaired after exercise; bones densify under stress. Psychologically, too, adversity builds resilience. Studies in developmental psychology show that children who face manageable challenges—whether physical, emotional, or intellectual—develop greater confidence and problem-solving skills than those shielded from difficulty. The concept of "antifragility," coined by Nassim Nicholas Taleb, captures this: systems, including people, don’t just withstand stress but thrive because of it.

Take the story of Viktor Frankl, a psychiatrist who survived the Holocaust. In his book Man’s Search for Meaning, he describes how prisoners in Nazi concentration camps found strength not despite their suffering, but through it. Those who endured unimaginable horrors often did so by clinging to a sense of purpose—whether it was reuniting with a loved one or bearing witness to humanity’s capacity for evil. Frankl argued that struggle, when met with meaning, transforms suffering into a source of inner power.

Contrast this with a life devoid of struggle. Imagine an existence where every need is met, every obstacle removed. At first glance, it sounds idyllic—no hunger, no conflict, no loss. Yet, such a life risks becoming stagnant. Without resistance, there’s no growth; without challenge, no triumph. The human spirit, forged in the fires of adversity, withers in perpetual ease. This isn’t mere speculation—research on “learned helplessness” shows that animals and humans alike, when stripped of agency and challenge, fall into despair. Struggle, it turns out, isn’t just a means to strength; it’s a prerequisite for a life worth living.

Purpose: The Compass Through Struggle

If struggle is the forge, purpose is the hammer that shapes it. A life without purpose is like a ship adrift—tossed by waves but going nowhere. Purpose gives struggle direction, turning raw hardship into something meaningful. This isn’t a new idea. Ancient philosophies, from Stoicism to Buddhism, emphasize that suffering is inevitable, but our response to it defines us. The Stoics saw obstacles as opportunities to practice virtue; Buddhists view suffering as a path to enlightenment. Both agree: purpose transforms struggle from a burden into a teacher.

Modern science backs this up. Psychologists studying post-traumatic growth find that people who endure trauma—cancer, war, loss—often emerge with a deeper appreciation for life, stronger relationships, and a clearer sense of what matters. The key? They find or create meaning in their pain. A soldier might dedicate himself to honoring fallen comrades; a cancer survivor might advocate for others. Purpose doesn’t erase struggle—it redeems it.

Conversely, a life without purpose feels hollow, even if it’s free of hardship. Depression rates soar in affluent societies where material needs are met but existential questions linger. The “paradox of prosperity” suggests that removing struggle without replacing it with meaning leaves us unmoored. We’re wired to strive, to push against something, whether it’s a physical limit, a societal injustice, or an inner demon. Without that tension, life loses its vitality.

Life Without Purpose Is No Life at All

This brings us to a stark truth: life without purpose is no life at all. A rock endures wind and rain but doesn’t grow stronger—it simply erodes. Humans, by contrast, are defined by our capacity to turn struggle into strength, but only if we have a reason to do so. The Moon didn’t just stir the tides; it set a rhythm that life adapted to. Evolution didn’t just kill the weak; it rewarded the resilient. Our personal struggles don’t just break us; they build us—provided we give them meaning.

Consider the alternative. A life of endless comfort, untested by adversity, might seem appealing until you realize it’s a void. No peaks without valleys, no victories without battles. The richest lives aren’t the easiest—they’re the ones tempered by struggle and guided by purpose. Nelson Mandela spent 27 years in prison, yet emerged not bitter but resolute, his purpose—to end apartheid—unshaken. Malala Yousafzai survived a Taliban bullet to champion education, her struggle amplifying her voice. These aren’t exceptions; they’re exemplars of a universal law: strength is born from struggle, and purpose gives it life.

So, embrace the tides of hardship, as our earliest ancestors did under the Moon’s watchful gaze. Let struggle sculpt you, as it did the creatures of the Cambrian seas and the savanna’s first humans. Seek purpose, as Frankl did in the darkest of times, for it’s the thread that weaves suffering into strength. Life isn’t meant to be easy—it’s meant to be strong. And in that strength, we find not just survival, but a reason to live.
