Twelfth Night, II. III. 47-52

"What is love? 'tis not hereafter;
Present mirth hath present laughter;
What's to come is still unsure:
In delay there lies no plenty;
Then come and kiss me, sweet-and-twenty,
Youth's a stuff will not endure."

--Twelfth Night, II. III,.47-52, William Shakespeare

Othello, III.III. 261-263

"Though her jesses were my dear heart-strings, I'ld whistle her off, and let her down the wind, To prey at fortune."

--William Shakespeare, Othello, act 3, scene 3, line 261-263

The Tempest, IV. I.150-157

"And, like the baseless fabric of this vision,
The cloud-capp'd towers, the gorgeous palaces,
The solemn temples, the great globe itself,
Yea, all which it inherit, shall dissolve,
And, like this insubstantial pageant faded,
Leave not a rack behind. We are such stuff
As dreams are made on; and our little life
Is rounded with a sleep."

--Shakespeare, The tempest, IV.I. 150-157
