Taylor Swift is the hottest act in country music. She's pretty much a rock star too, with her recent country chart-toppers, 'Love Story' and 'You Belong with Me' crossing over to become huge pop hits. At 19, her first headlining tour is a coast-to-coast smash -- she sold out New York's Madison Square Garden and the STAPLES Center in Los Angeles.

But ask Taylor what the toughest thing she's ever had to do so far is, and she says it was leaving high school.

"That was a tough thing, to make that decision and realize that I was not going to graduate in a graduation ceremony," Taylor tells The Boot. Though she graduated in July 2008 through a home-schooling program, Taylor still can't help but reflect, "You have all these perceptions and dreams that you're gonna throw your cap in the air ... I walked out of 10th grade one day, and had to come to terms with the fact that I was never gonna wear a cap and gown. I think of all the things that you consciously have to do -- ending a period of time in your life that most people experience -- that was pretty tough."

But like the title of her multi-platinum album (coming out in a deluxe version on Oct. 27) and global tour, Taylor is fearless these days about all of the things she's doing in her career -- and all the face time she's getting on TV. The singer-songwriter (and CMA Entertainer of the Year nominee) recently appeared on 'The Oprah Winfrey Show,' and is scheduled to appear on 'Dancing with the Stars' on Oct. 27, and 'The Ellen DeGeneres Show' on Oct. 29. She's also hosting 'Saturday Night Live' on Nov. 7, just days before the CMA Awards on Nov. 11.
