LIBRA (Sept. 23-Oct. 22): One of the world's best race car teams, McLaren, wins about 25 percent of the events in which it competes. Its skilled drivers account for much of its success, but its technicians are also sensational. During a pitstop in the middle of a race, they can change all four tires in less than three seconds. Do you have helpers like that? If you don't, it's time to intensify efforts to get them. If you do, ask them for an extra boost.
