Peter Pan 

Peter Pan's syndrome (do latim: Puer aeternus) is characterized by individuals who can't see themselves as adults and take their obligation seriously. They have childish and irresponsible behavior as they seem to lose track of reality. 

It is still difficult to admit that we can't live forever and live eternal adventures without some sense of engagement and liability. 

But isn't that the fun part of being a grown up? Making every moment count? Creating the things that outlast you. 

We must be true to ourselves and others in the pursuit of our happiness and growth. 

That's what being a grown up is. Taking a hold of our fate and not relying on others to do so. 

So just… grow up!
