World's youngest self-made woman billionaire shares her routine, says 'I've more hrs in a day'
Lucy Guo, the world's youngest self-made woman billionaire, wakes up at 5:30am, exercises for two hours and has lunches during meetings as her schedule doesn't allow breaks. "I've more hours in a day because...I don't need that much sleep...9am to 9pm, to me that's still work-life balance," she said. She takes six hours a day on weekends to meet friends.
