An "adult" is a person who has reached a certain age, typically 18 or older, when they are considered fully grown and responsible for their own actions. Adults have the ability to make important decisions, such as choosing a career, managing finances, and forming relationships. They often take on roles like parent, employee, or citizen, contributing to society in various ways. Being an adult also means facing challenges and responsibilities. Adults must balance work, family, and personal interests while navigating life's ups and downs. They often seek independence and strive for personal growth, learning from experiences to become better versions of themselves.
