Adults are obsolete children. 
-Dr. Seuss
 
Man's maturity: to have regained the seriousness that he had as a child at play.
 
When I grow up I want to be a little boy. 
 
 
Going into maturity is not forsaking the child in you:)
 
When i grow up, i want to be a little girl that's as serious as that i had as a child at play.
-Adeline Adella
