Some millionaires reach seven figures through hustling and penny pinching.
Graffiti artist David Choe knows the second scenario well.
As featured on a recent episode of CNBC's "The Filthy Rich Guide, " in the early 2000s, Choe's work caught the eye of Sean Parker, founder of Napster.
In 2005, after Parker became president of then-fledgling start-up Facebook, he hired Choe to deck out its original headquarters in Silicon Valley with murals.
Though Choe despised social media's early iterations like MySpace and called Facebook a "ridiculous" idea, according to "The Filthy Rich Guide," he agreed to paint the building for a hefty sum: $60,000.
"My prices had been going higher and higher and I was like, 'Yeah, I mean, if you want me to paint the entire building, it's going to be 60, you know, 60 grand,'" Choe told Howard Stern. »
