Michelle Trachtenberg may have one of the coolest jobs in showbiz, but it's a lot of hard work.

"I've met kids my age, younger and older, and they're like, 'Oh, congratulations - you're in such a glamorous business,'" she tells TV Guide. "But y'know, it's not that glamorous if you actually stop for a minute and think about it. There are tons of sacrifices."

"I guess I'm hungry for it - I love to pile a lot of things on," she adds. "I love being in front of the camera, and education is very important to me, too, so I couldn't give either of them up."

Despite the prospect that she could become the show's star if Buffy goes to an eighth season, Michelle is grateful for the opportunities. "I'm getting a wonderful education and working a full-time job; and I also have time to crash in front of the TV occasionally."
