Adolescence to adulthood is a significant developmental stage that typically occurs between the ages of 12 and 24. During this period, individuals experience physical, emotional, and social changes as they transition from childhood to adulthood. Key developments include the onset of puberty, increased independence, and the formation of identity. This stage is marked by important milestones such as completing high school, pursuing higher education or vocational training, and entering the workforce. Social relationships evolve, with friendships becoming more complex and romantic relationships often beginning. These experiences help shape an individual's values, beliefs, and future goals.
