Dear Jack...

"All work and no play makes Jack a dull boy."

I heard of this proverb before but I didn't know there is a brilliant follow-up to it! lol...

"All play and no work makes Jack a mere toy."

Well, I would rather be a mere toy than a dull boy. :)

And one more, the cynical version: "All work and no play makes Jack. And plenty of it." XD
(Jack here is a slang used metaphorically to mean $$$)
