From William Shakespeare (1564–1616), English poet, playwright, and actor, Hamlet, (1601):
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 ownself be true.
And it must follow, as the night the day,
Thou canst not then be false to any man.
Polonius, Act I, scene iii.
This seems particularly good advice right now, both about not borrowing and lending, and being true to thine ownself.
