The varying shore o’ th’ world!”

“To be worst,
The lowest and most dejected thing of fortune,
Stands still in esperance, lives not in fear.
The lamentable change is from the best;
The worst returns to laughter. Welcome, then,
Thou unsubstantial air that I embrace!
The wretch that thou hast blown unto the worst
Owes nothing to thy blasts.”
—William Shakespeare (1564–1616)
