The key to success is believing you will succeed. Just ask Dolly Parton:
Parton grew up the 4th of 12 children in a tin-roofed shack in East Tennessee's Appalachian mountains. During her teenage years Parton and her mother's brother, Bill Owens, also a songwriter, would venture into Nashville and try to get signed. "We used to come down in his rickety car any time we could beg, borrow, or steal enough money for gas," Parton remembers. "We'd clean up in service stations. I'd wash my hair in those old, cold sinks and put my makeup on in the mirrors in the car." Through it all, she says, "there wasn't ever a time I thought I wasn't going to make it."
