Comedian and former host of NBC's "The Tonight Show" Jay Leno plays it safe when it comes to money .
From the moment he entered the working world, "I always had two incomes," he explains to CNBC.
"When I was younger, I would always save the money I made working at the car dealership and I would spend the money I made as a comedian," he says.
"When I got 'The Tonight Show,' I always made sure I did 150 [comedy show] gigs a year so I never had to touch the principal," Leno says.
"I've never touched a dime of my 'Tonight Show' money.
Leno, who now hosts CNBC's " Jay Leno's Garage ," says his conservative philosophy gives him financial peace of mind.
"So many people get to be the age I'm at now and they've got nothing because they just blew it all," he says. »
