Happiness is retiring to the country with your friends

 All hail, ye fields, where constant peace attends!

All hail, ye sacred, solitary groves!

All hail, ye books, my true, my real friends,

Whose conversation pleases and improves!

-- William Walsh (1663-1708)

Happiness is a silver saucepan

 If your butter when melted tastes of brass, it is your master's fault who will not allow you a silver saucepan. 

-- Jonathan Swift

Happiness is the word queue

 

Happiness is freedom from anxiety

 To be happy, is not only to be freed from the pains and diseases of the body, but from anxiety and vexation of spirit; not only to enjoy the pleasures of sense, but peace of conscience, and tranquillity of mind.

-- John Tillotson (1630-1694)
