Tis in my memory lock'd, And you yourself shall keep the key of it. - William Shakespeare

Have more than thou showest,
Speak less than thou knowest,
Lend less than thou owest,
Ride more than thou goest,
Learn more than thou trowest,
Set less than thou throwest

And what’s he then that says I play the villain?

How does your patient, doctor?

Doctor: Not so sick, my lord, as she is troubled with thick-coming fancies that keep her from rest.

Macbeth: Cure her of that! Canst thou not minister to a mind diseased, pluck from the memory a rooted sorrow, raze out the written troubles of the brain, and with some sweet oblivious antidote cleanse the stuffed bosom of that perilous stuff which weighs upon her heart.

Doctor: Therein the patient must minister to himself.
