When Dolly Parton was young, her mother gave her a piece of advice: "Always keep something back for you."

Those six words have helped the 76-year-old country music superstar maintain success through six decades of showbusiness, Parton told Apple Music Country's "The Kelleigh Bannen Show" on Tuesday. The phrase, which applies equally to business and work-life balance, essentially means give to others, but meet your own financial and emotional needs first — and Parton said any young person could benefit from that lesson.
