Don't expect to find Ronit Rogoszinski in meetings, entertaining clients or hunched over her desk around lunchtime. The 45-year-old wealth adviser and financial planner in New York describes herself as an expert "practitioner of the power nap." After waking up at about 5 a.m., sending her kids off to school and putting in a morning of meeting with clients, Rogoszinski needs to crash. "By noon, my brain starts to fry," she says. So she heads to one of her hideouts -- her car, for example -- to recharge. As she puts it, "I'm not quite sure how I'd handle the day without that timeout."
