Book excerpt: As an eminent authority in the field of development, Dr. Colarusso calls on his 30 years of clinical experience to provide us with a thorough understanding of the changing biological, psychological, and environmental conditions that we face throughout our lives. He arms us with knowledge that will help us maximize the pleasures and avoid the pitfalls that each new phase of life brings - particularly the anxieties and disappointments of midlife. Guiding us through a wealth of facts, Dr. Colarusso shows us the smoothest and most direct paths to adult fulfillment. He demonstrates that an enriched, rewarding life is one in which the triumvirate of human experience -love, work, and play - are balanced. By learning from the concepts of this burgeoning science and the detailed case histories - including one of a 70-year-old grandmother - we find that it is never impossible or too late to achieve happiness and fulfillment.
