orum, an art gallery, a wine distributorship, a funky Mexican restaurant, a chain of airport-based music stores, among others and kept them going. Their firsthand experience is the core of the book, which follows the approach of Lieber's Taking Time Off, which advised college students by example in how to carefully tune in and temporarily drop out. While this is not a comprehensive, detailed handbook, the savvy tips of Lieber's interviewees acquaint tyros conceptually with a variety of standard business practices. They offer such basics as "Do What You Know," as one acne-prone woman now runs a thriving skin-care spa notes, to do-it-yourself market research, like that of a swimwear designer who apprenticed in retail to find out what women really wanted.

This upbeat primer will serve as a springboard for readers of any age, though some of less sunny casts will scoff at its lack of fatal mistake-makers. Editor, Suzanne Oakes; agent, Anne Edelstein.
