Everyone loves a good rags-to-riches story, and Elon Musk's got a pretty compelling one. Back in 2018, he took to X (then called Twitter) to spell out exactly how he went from teenage immigrant to tech billionaire.

The story starts with Musk at 17, landing in North America with $2,000 to his name, a backpack, and a suitcase stuffed with books. He first settled in Canada, using his mother's birthright to secure a passport, before heading to the United States on a scholarship to the University of Pennsylvania.

"I arrived in North America at 17 w $2000, a backpack & a suitcase full of books. Paid my own way thru college. Dropped out of Stanford Eng/Phys grad school w $110k in college debt. Created Internet startup," Musk wrote.

He paid his own way through college and briefly attended Stanford's graduate program for engineering and physics before dropping out with $110,000 in student debt. Not exactly the cushiest starting point.

Musk originally wanted to work at Netscape Communications, but when that didn't pan out, he did what ambitious people do when they can't get hired: he started his own company. That company was Zip2, founded in 1996 with the goal of bringing media companies online. His experience running Zip2 in the 1990s gave him insights into how newsrooms work, knowledge he's referenced when discussing plans for Pravduh, a platform designed to rate journalist credibility.

After Zip2, Musk co-founded PayPal, then moved on to establish SpaceX and Tesla, building a fortune exceeding $20 billion. Even with that kind of success, he hasn't stopped innovating. He's recently unveiled details about a SpaceX version of the Tesla Roadster supercar, because apparently running multiple revolutionary companies simultaneously isn't enough.

The whole trajectory demonstrates what relentless drive and willingness to take risks can accomplish. From $2,000 and some books to reshaping multiple industries, it's the kind of story that shows how far entrepreneurial ambition can actually take you.
