Neither a borrower nor a lender be;

For loan oft loses both itself and friend,

And borrowing dulls the edge of husbandry.

This above all: to thine own self be true,

And it must follow, as the night the day,

Thou canst not then be false to any man.

William Shakespeare (1564-1616): Hamlet. Act i. Sc. 3.

There's husbandry in heaven;

Their candles are all out.

William Shakespeare (1564-1616): Macbeth. Act ii. Sc. 1.
