“Another conceptual theme draws attention to the role of individuals in their own development. Here, we delve into the complex ways in which young people select into personal experiences, interpersonal rela- tionships, and social settings in ways that reflect their past and contribute to their futures. As we discuss, this process of selection of person occurs through the agentic strivings of individuals as well as through the interplay of environment and biology.” (from Insights on Adolescence From a Life Course Perspective)

I love this passage. So many sources and research on adolescence study this period of life as a very linear stage of development that is similar across different cultures and environments. There is a notion that adolescence consists of stages and milestones of development that are universal. However, perhaps more than any other period of life, the teenage years are so varied and shaped by so many different factors. One of the most important is certainly the individual, and what an individual wants, what goals he or she has, how they see themselves, etc. So many factors in adolescence are dependent on motivation and the power of the individual. Knowing this can be very empowering, and this school of thought is more comprehensive in that it places the focus on the individual in general.
