Mature people—youth or adults—live by values. They have principles that guide their decisions and are able to progress beyond merely reacting to life's options. They live proactively. Although they recognize their emotions as important, their character is master over their emotions. A mature person acts like they know what they want and are not afraid to go after it. They know how to handle themselves and are not afraid to speak their mind. They are confident and know how to take care of themselves. They are also not afraid to show their emotions.
