An exclamation or statement expressing the sentiment that one should never become so grown-up that one loses the ability to be childish.

Longer expressions that mean the same thing:
"Never get so battle-fatigued that you can't enjoy your shore-leave."
"Never work so hard to provide for your kids that you lose the ability to play with them."
