Happiness is January, right Jack?

 

Happiness is an extremity you'll do well to avoid

 The East and West

Upon the globe, a mathematick point

Only divides: thus happiness and misery,

And all extremes, are still contiguous.

 

-- Sir John Denham (1614/15-1669) 

Happiness is roast beef and gravy on a Tuesday, a lousy Tuesday

 

Happiness is my green tambourine: The Lemon Pipers, November 1967

Drop your silver in.
