Happiness is a wine of the rarest vintage, and seems insipid to a vulgar taste.
— Logan Pearsall Smith

Pleasure that isn't paid for is as insipid as everything else that's free.
Anita Loos insipid quote

Now everything changed. My childhood world was breaking apart around me. My parents eyed me with a certain embarrassment. My sisters had become strangers to me. A disenchantment falsified and blunted my usual feelings and joys: the garden lacked fragrance, the woods held no attraction for me, the world stood around me like a clearance sale of last year's secondhand goods, insipid, all its charm gone. Books were so much paper, music a grating noise. That is the way leaves fall around a tree in autumn, a tree unaware of the rain running down its sides, of the sun or the frost, and of life gradually retreating inward. The tree does not die. It waits.
— Hermann Hesse

Tea! Thou soft, thou sober, sage, and venerable liquid, thou innocent pretence for bringing the wicked of both sexes together in a morning; thou female tongue-running, smile-smoothing, heart-opening, wink-tipping cordial, to whose glorious insipidity I owe the happiest moment of my life, let me fall prostrate thus, and . . . adore thee.
— Colley Cibber

If I had my life over again I should form the habit of nightly composing myself to thoughts of death. I would practice, as it were, the remembrance of death. There is no other practice which so intensifies life. Death, when it approaches, ought not to take one by surprise. It should be part of the full expectancy of life. Without an ever-present sense of death life is insipid. You might as well live on the whites of eggs.
— insipid quotation by Muriel Spark
