Have you ever thought, "Why didn't I think of that?" Yep, me too. Recently, I had one of those "WDITOT" moments when I read about Lauren Luke, a British woman who's risen to YouTube stardom by recording simple makeup tutorials. The one-time cab dispatcher started off in the biz by selling makeup on eBay. In order to cater to her customer's questions, she started doing video tutorials on YouTube. Her channel, Panacea81, has 4.5 million viewers. Next month, her own cosmetics line is due in stores and she's also got a book coming out in October. Pretty amazing, eh? Check out her work below. And as Luke would say in her signature sign-off, "Zoom, zoom."
