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), British poet. Hamlet (I, iii).
