Billionaires aren’t all born with a silver spoon in their mouth.
In fact, many came from nothing at all.
The “rags-to-riches” trope may be a cliché, but it’s one that’s definitely grounded in reality for some famous billionaires.
Through extraordinary grit and perseverance, individuals across the globe have beat the odds and achieved their own rags-to-riches stories.
Here are 19 people who started off life poor and went on to become billionaires:
Guy Laliberté was a fire-eater before founding Cirque du Soleil
Net worth: $1.19 billion
At the beginning of his career, Laliberté had fire in his belly — literally. The Canadian-born circus busker played the accordion, walked on stilts, and ate fire.
Later on, as Business Insider previously reported, he took a chance and flew a troupe from Quebec to Los Angeles without purchasing a return fair. The circus troup traveled to Las Vegas and became Cirque du Soleil.
Laliberté is now the CEO of Cirque de Soleil.
Kenny Troutt, the founder of Excel Communications, paid his way through college by selling life insurance.

He’s now retired and invests heavily in racehorses.

Born into a nomadic tribe in the Syrian dessert to a poor mother who was raped by his father and died when he was young, Altrad was raised by his grandmother. She banned him from attending school in Raqqa, the city that is now capital of ISIS.
Altrad attended school anyway, and when he moved to France to attend university, he knew no French and lived off of one meal a day. Still, he earned a PhD in computer science, worked for some leading French companies, and eventually bought a failing scaffolding company, which he transformed into one of the world’s leading manufacturers of scaffolding and cement mixers, Altrad Group.
He has previously been named French Entrepreneur of the Year and World Entrepreneur of the Year.
Born into poverty, Oprah Winfrey became the first African American TV correspondent in Nashville.

Starbucks president Howard Schultz grew up in a housing complex for the poor.
Net worth: $2.9 billion
In an interview with the Mirror, Schultz said: “Growing up I always felt like I was living on the other side of the tracks. I knew the people on the other side had more resources, more money, happier families. And for some reason, I don’t know why or how, I wanted to climb over that fence and achieve something beyond what people were saying was possible. I may have a suit and tie on now but I know where I’m from and I know what it’s like.”
Schultz ended up winning a football scholarship to the University of Northern Michigan and went to work for Xerox after graduation. Shortly after, he took over a coffee shop called Starbucks, which at the time had only 60 shops. Schultz became the company’s CEO in 1987 and grew the coffee chain to more than 16,000 outlets worldwide.
