If your responsibilities have been weighing on you heavily, you might benefit from allowing yourself a little time to goof off. Watch a silly movie you used to love as a kid. Listen to your old favorite songs. Spend time with people who crack you up. The freedom and carelessness of childhood doesn’t have to be completely eradicated from your life just because you’re grown up. Being a responsible mature adult is obviously important, but being occasionally carefree is too.
