You know the people described in "Home Away From Home." They're the classic overachievers, and every work place has them: "They are dedicated, conscientious, capable, loyal and will do everything in their power to please." They are valuable and productive employees, and their success is predictable; it's also a mixed blessing.These people are children of alcoholics, and what's really driving them is not just the healthy instinct to succeed but a deep-seated conviction that no matter how well they do their jobs, it won't be good enough to earn the approval and respect they so desperately need.
