Wynonna is sounding off about her feelings on the "quick success" that 'American Idol' seems to promote.

"First of all, you have to have a gift," she told students at Nashville's Belmont University recently, as reported by GAC. "This whole thing about making it overnight -- come talk to me, and I can tell about how that doesn't work. It looks real easy, but boy oh boy. And then when you make it like me, you win the lottery and have to spend your whole life catching up."

Wynonna says she's concerned that many 'Idol' contestants aren't prepared for the instant fame that comes with the show.

"A lot of these people don't have experience and they're not ready. When they're successful, they're like, 'Oh, crap, what do I do now?' So they hire a bunch of people who cost them everything," said the country star, who's enjoyed more than 20 years of success in the business. "So develop it now, start getting a work ethic, schedule your priorities," she advised. "Focus, focus, focus on what it is you really wanna do."
