BAZAAR chatted with Licht about her new book and best career advice-which she shared all in 140 characters or less, of course. Leave Your Mark promises to guide you through landing your dream job, killing it in your career and rocking social media-and it does just that through 19 chapters that should serve as any young professional's go-to handbook, full of real-life advice that you won't learn in a classroom. Leave Your Mark chronicles Licht's career path from her days as a pre-med student to her time interning at fashion magazines to her foray into social media at Donna Karan-all written in the same authentic tone as her Twitter feed. If you've been one of her loyal Twitter followers (or as she refers to them, 'Twitter friends') you'll be happy to know that her 140-character limit just got a major extension, to 288 pages in a new tell-all mentorship book that makes its debut today.

Licht has cemented her status in the Twittersphere by becoming the ultimate source for behind-the-scenes fashion/celebrity scoop, career advice and even a friend to chat with while live-tweeting shows such as Gossip Girl and Scandal. What started out as just 140 characters has evolved into so much more.

Fast-forward to today and Aliza Licht, the voice and brains behind DKNY PR Girl, has created a social media empire that has amassed half a million loyal Twitter followers, four consecutive Fashion 2.0 awards for 'Best Twitter,' her own TED Talk and now her first book, Leave Your Mark. Before social media was even a factor in the fashion industry, there was DKNY PR Girl-an anonymous Twitter account that started it all in 2009.
