I think both have advantages and disadvantages. Being a child allows you to live with no worries; you just enjoy playing in your most time, and you have curiosity about everything, which will make you motivated to explore the world. But sometimes you must follow your parents’ instructions and don’t do anything they forbid. As an adult, it is evident that you have more choices by yourself. You can choose your interests. You have more freedom and capabilities to do those things. But you also need to respond to the results on your own. So I think the best way is to accept every moment you have experienced and enjoy your current life.
