Gifted Men and Women Define Success Differently, 40-Year Study Shows
Researchers spent four decades studying a group of mathematically talented adolescents, finding that by mid-life they were extraordinarily accomplished and enjoyed a high level of life satisfaction.Gender, however, played a significant role in how they pursued — and defined — career, family, and success.
