Doing whatever it takes to make you happy and for some people, at least they're being who they are and not the stereotype of who they're supposed to be. Your inner child. Most people believe that age defines who you are and if you don't "act your age", you're immature. "Mature" people seem to be very depressed and settle for everything even if they don't want it.

Other person: At least she's doing what makes her happy, bitch.
