“Just because I’m blonde, don’t think I’m dumb,” coos Dolly Parton in the opening song on Hello, I’m Dolly, her debut album in 1967. “‘Cause this dumb blonde ain’t nobody’s fool.”

And Parton certainly isn’t. But anyone who knows that Parton is a Capricorn, born on January 19th, and that Capricorns are — as astrologer Susie Cox writes in her book Susie’s Sun Signs — “the most driven and dedicated of all the zodiac signs” could have told you that. After all, this is someone who pulled herself up from a stone-broke childhood in the rural Smoky Mountains to become a top-selling country icon (with her own theme park to boot). You don’t get there by luck; it takes hard work and fire-in-the-belly ambition.

“Capricorns are astrology’s overachievers and will work until they reach their goals,” Cox continues, highlighting their natural sense of clout. “Halfway just won’t cut it…. Capricorns have a plan, and their goal is to do it, whatever it is!”

In talking about her past and how she wrote her first songs at five and recorded her first single at 10, Parton once told The Washington Post that she “was born with a God-given talent, something I recognized very, very early and started usin’…” She adds, later in the 1978 interview, “I knew I had to do somethin’ in life and that I would do it.”

Sound familiar?

But Parton does stray from the Capricorn pack in one regard. While “Capricorns all pay attention to their appearance and always want to look good,” Cox notes that their fashion sense tends towards the conservative and the classic: “No wild colors or patterns for this earth sign.”
