Sonnet 26

Sweet is the rose but grows upon a briar;
Sweet is the juniper, but sharp his bough;
Sweet is the eglantine, but pricketh near;
Sweet is the fir bloom, but his branches rough;
Sweet is the cypress, but his ryndd is tough.

Sweet is the nut, but bitter is his pill;
Sweet is the broom flower, but yet sour enough;
And sweet is moly, but his root is ill.

So every sweet with sour is tempered still.
That maketh it be coveted the more:
For easy things that may be got at will,
Most sorts of men do set but little store.
Why then should I account of little pain,
That endless pleasure shall unto me gain.

- Edmund Spenser
