While a lot of rock stars seem to be allergic to saving the money they earn, that's not the case with Foo Fighters leader Dave Grohl. The musician learned a long time ago to save every penny, just in case this whole rock band thing doesn't last.

Speaking to The Big Issue (via Rock AAA), Grohl recalls how his father taught him an important money lesson when he was young.

“When Nirvana first became popular, my father gave me the best advice. He said, ‘Treat every f____ check like it’s the last one you’re ever going to make, because this isn’t going to last.’  So I don’t throw it around like Puff Daddy. Just so you know, I still treat every check I get like it’s going to be the last."

Grohl went on to say that he is uncertain about the future beyond music.

“That’s burned into my brain. I’m a high school dropout and if this ever ends I don’t know what I’m going to do. I don’t even have a high-school diploma!"

Foo Fighters announced this week that they will embark on a fall tour with Rise Against and Mariachi el Bronx, stopping by the Palace of Auburn Hills September 19.

Maybe Grohl could follow the footsteps of Duff McKagan and become a financial advisor.
