More than 1.3 million students drop out of high school every year in the US, making them ineligible for 90% of jobs in America,according to DoSomething.org.
But while it's by no means considered the path to success — Tumblr founder David Karp dropped out of high school at the age of 15 and told Forbes he doesn't recommend it to others since he missed out on so much — some people made the most of their time outside the hallowed halls of high school.
Here is the special breed of super successful people that overcame their "high-school dropout" status and turned the world on its head.

Called an "unsung hero of the internet," the supercomputer scientist dropped out of high-school in Nigeria due to war conditions and lack of tuition money. According to Time, he was considered a math prodigy and continued to study on his own, earning an equivalency diploma and later a scholarship to Oregon College of Education in the US.
In 1987, Emeagwali came up with the formula for allowing a large number of computers to communicate at once. The record-breaking experiment was a practical and inexpensive way to use machines to speak to each other all over the world.
The discovery earned him the IEEE Gordon Bell Prize in 1989, and he has since been hailed as one of the fathers of the Internet, according to Time.
Quentin Tarantino dropped out at 15.
The Oscar winner attended Narbonne High School in Harbor City, California, until he dropped out at the age of 15 and started working as an usher at an adult film theater while taking acting classes, according to Bio.
While working at the Video Archives in his early 20s, Tarantino wrote the scripts for "True Romance" and "Natural Born Killers," but it was his directorial debut in "Reservoir Dogs" in 1992 that won him wide critical acclaim.
He's been nominated for several Academy Awards and is the winner of two — for "Django Unchained" and "Pulp Fiction."
Francois Pinault dropped out at 11.
According to Forbes, the French businessman dropped out of his private high school in 1947 to work at his father's lumber mill in part because his school mates made fun of his poor background.

He also owns Christie's Auction House and is currently worth around $12.9 billion,according to Forbes.

The self-made billionaire businessman dropped out of high school in the ninth grade and worked at a gas station before being drafted into the Army in 1943,according to Forbes.
After World War II, Murdock bought his first business, a Detroit diner, and sold it several months later for a $700 profit. Now, after a lifetime of buying, building and selling, he's worth an estimated $2.9 billion,according to Forbes.
The Dole Foods CEO took the company private in 2013 in a deal that valued the company at $1.6 billion.
At 92, Murdock is somewhat of a health nut — he told the New York Times he swore off red meat long ago and eats as many as 20 fruits and vegetables a day, going so far as to pulverize banana peels and orange rinds into the smoothies he drinks two to three times a day — and he says he wants to live forever.

He has been inducted into the World Boxing Hall of Fame and the International Boxing Hall of Fame as a two-time World Heavyweight Champion and Olympic gold medalist.
Most of Foreman's fortune came after his boxing career as a spokesperson for Russell Hobbs Inc.'s fat-reducing grill called the George Foreman Grill, which has earned him an estimated net worth of $250 million, according to TheRichest.
