Edmund Spenser
Amoretti: Sonnet 26
Sweet is the Rose, but growes upon a brere;
    Sweet is the Junipere, but sharpe his bough;
    sweet is the Eglantine, but pricketh nere;
    sweet is the firbloome, but his braunches rough.
Sweet is the Cypresse, but his rynd is tough,
    sweet is the nut, but bitter is his pill;
    sweet is the broome-flowre, but yet sowre enough;
    and sweet is Moly, but his root is ill.
So every sweet with soure is tempred still,
    that maketh it be coveted the more:
    for easie things that may be got at will,
    most sorts of men doe set but little store.
Why then should I accoumpt of little paine
    that endlesse pleasure shall unto me gaine.
