Adversity
The storms of adversity, like those of the ocean, rouse the faculties, and excite the invention, prudence, skill and fortitude of the voyager.
—Captain Marryatt
Sweet are the uses of adversity,
Which, like the toad, ugly and venomous,
Wears yet a precious jewel in his head.
—William Shakespeare
