Success stories inspire us, but we often overlook the relentless struggles behind them. Many legendary achievements began with rejection, doubt, and unimaginable hardship. Let’s explore a few powerful stories that show how persistence, belief, and relentless effort can turn failure into greatness.
The Ten-Year Fight for Squid Game
In 2009, Hwang Dong-hyuk had a vision. He wrote a script for a survival drama about human desperation, capitalism, and the lengths people would go to for money. The story was dark, unconventional, and deeply unsettling. Studios rejected it for a decade, deeming it too unrealistic.
In those years of rejection, Hwang faced severe financial struggles. He even had to sell his laptop just to survive. Imagine the despair of watching your dream crumble while the world dismisses your vision. Yet, he did not give up.
In 2021, after ten long years, Squid Game finally found its way to Netflix. It became a global sensation, topping the charts in 93 countries and earning over $900 million. Hwang’s persistence paid off, proving that even the most radical ideas can find success if you refuse to quit.
From Handwritten Pages to a Magical Empire

Today, J.K. Rowling is one of the most famous authors in the world, but her journey to fame wasn’t paved with gold. Before Harry Potter, Rowling was a single mother living in poverty. She didn’t even have enough money to buy a typewriter, so she wrote the first manuscript by hand.
When she finished her story, publishers rejected it—twelve times. Critics dismissed her book about a young wizard as unmarketable, claiming there was no audience for such fantasy tales.
Rowling persisted. When one publisher finally took a chance on her, Harry Potter and the Philosopher’s Stone changed literary history. The series has sold over 500 million copies, been translated into more than 80 languages, and evolved into a billion-dollar film franchise. Her story is a testament to the power of perseverance, imagination, and unwavering belief in your work.
The Man Who Fried His Way to the Top
Colonel Harland Sanders, the founder of KFC, didn’t see success until he was 65. His life was filled with failure after failure—so many that it defies counting. At an age when most people consider retirement, Sanders created a fried chicken recipe he believed in.
With little more than his recipe and sheer determination, he traveled across the United States, pitching his fried chicken idea to restaurants. He was rejected over 1,000 times. Imagine hearing “no” again and again at that age, yet still finding the strength to keep going.
Today, KFC operates in over 145 countries with more than 24,000 outlets. Colonel Sanders’ journey shows that it’s never too late to succeed if you have passion and persistence.
Success Is Never a Straight Road
When we hear stories of triumph, we rarely see the mountains of failure beneath them. Success isn’t easy—it’s full of setbacks, heartbreaks, and moments when giving up feels inevitable. But that’s exactly what makes success valuable.
In The Unfair Advantage, the authors describe one type of successful person: someone whose only path to triumph is relentless hard work. The question is, are you willing to walk that rocky road?
The next time you face rejection or failure, remember the stories of Hwang Dong-hyuk, J.K. Rowling, and Colonel Sanders. Success comes to those who persist when others give up. Are you ready to put in the hard work?
