Taylor Swift was a precocious and talented teen on the verge of superstardom when she made her debut her first single 'Tim McGraw' back in 2006. Now of legal drinking age at 22, her fans and the music industry have watched this singer-songwriter grow from sugary-sweet love songs such as 'Love Story' and 'Sparks Fly' to more adult material like 'Mine,' 'Better Than Revenge' and her second single from 'Red,' 'Begin Again.'

During a recent interview with Esquire, Swift made it clear that she has managed to balance her wholesome image with her new-found adult freedom. Though she's technically old enough to drink, you likely won't find her getting sloshed in bars or drunkenly crashing her car like many of her same-aged peers.

"I don't drink much alcohol," the 'WANEGBT' hitmaker reveals. "If it doesn't taste like candy or sparkles, I usually don't drink it." When asked if the singer drinks scotch, she says no, but doesn't rule it out forever. "Wine sometimes, because it makes me feel classy, but not Scotch," Swift says. "Not yet."

Though she has enjoyed massive success over the past six years, Swift's career is still blazing hot. Her debut single from 'Red,' 'We Are Never Ever Getting Back Together,' was certified platinum by the Recording Industry Association of America (RIAA), and the single debuted at the top of the Billboard Hot 100 -- a big feat, even for her.

"Yeah, to have that happen was a serious jumping-up-and-down-screaming moment for me. I didn't want to peak at 18," Swift admits. During a previous interview with ABC's 'Nightline,' the superstar acknowledged she is a worrier at heart; she re-emphasized that in her chat with Esquire.

So does this six-time Grammy Award winner worry that she is experiencing the peak of her career now, at age 22? "I'm always worried about everything. Like spiders. Right now, I'm worried about that," she says somewhat evasively.

One thing Swift isn't worried about? Running out of heartbreak songs or song inspiration. "This is breaking news, but there are a few happy songs on this album ['Red']," she reveals jokingly. "I do explore the emotion every once in a while. I'd like to think you don't stop being creative once you get happy. My ultimate goal is to end up being happy."

She adds poignantly, "Most of the time."
