Define GROWING UP

You know, some times I always think about how people grow in size but never ever mature. They don't become more resourceful, thoughtful, caring. They don't grow in both IQ or EQ. Or perhaps they do improve on their IQ but not EQ.

How do you gauge growth? By size or by their maturity? It doesn't mean that a person after 21 is grown up. Yes, they are legally an adult. But they aren't literally.
