Foo Fighters front-man Dave Grohl got his start as one-third of the iconic grunge band Nirvana in the early 1990's. Since then, he has won Grammy awards, produced films and worked alongside some of the biggest names in music, including Paul McCartney and Led Zeppelin's John Paul Jones. It's safe to say Grohl's success is well-earned — but, though he enjoys the benefits of his lucrative career, he still watches his spending. When asked what he does with all his cash during an interview with The Red Bulletin, Grohl said, "It goes straight into my bank account, where it turns all moldy and smelly." Even when Nirvana hit it big and Grohl got his first credit card, he stayed frugal. His inaugural purchase on the card was a dinner at Hibachi chain Benihana.

Though he says that money allows him the freedom to pursue the projects he wants without worry, it's never his top priority. "I don't waste my time thinking about how I could make more when I already got enough," he tells The Red Bulletin. "I'm not a banker, I'm a musician." That viewpoint carries over into his personal life as well: "I drive a family car — not a monster SUV, but a family car that fits five people," he says. "I've got a house that is just big enough, too." Grohl is not pure practicality: He also owns a $140,000 Tesla which he acknowledges is 'impractical' and 'the stupidest thing.' The musician's overall mindset about money was formed at a young age when his mother, a public school teacher, had a stroke while filing her taxes. "I remember coming back to the house that night, alone with my sister and looking at the piece of paper she was writing to the IRS on as she started to have her stroke," he told The Guardian in 2014. "And it left this indelible mark on me that was 'Money will kill you', that people spend their lives dying inside because of money."
