“Early Adulthood (Ages 20-35): Enterprise – It takes enterprise for young adults to accomplish their many responsibilities, including finding a home and mate, establishing a family or circle of friends, and/or getting a good job.
Midlife (Ages 35-50): Contemplation – After many years in young adulthood of following society’s scripts for creating a life, people in midlife often take a break from worldly responsibilities to reflect upon the deeper meaning of their lives, the better to forge ahead with new understanding.”
