Nightingale-Conant's AdvantEdge If you want some helpful business tips from some smart folks with sunny dispositions, consider subscribing to this little-known periodical. Nightingale-Conant's AdvantEdge magazine is published by the makers of motivational CDs and books, so it's loaded with simple, upbeat lessons. (See the "Fine Print" column in Upfront Business, p. 68, for a quote from the premiere issue.) The investment is small for one- and two-year subscriptions—less than the cost of a week's worth of lunches in the Big Apple. You can check out the table of contents online at www.nightingaleconant.com.
