Yond Cassius has a lean and hungry look;
He thinks too much: such men are dangerous.

Julius Caesar

A friend should bear his friend’s infirmities.

William Shakespeare Wikipedia: William Shakespeare  

Julius Caesar, act 4, scene 3, Cassius

A gentleman that loves to hear himself talk, will speak more in a minute than he will stand to in a month.

A good old man, sir. He will be talking. As they say, when the age is in, the wit is out.

A little more than kin, and less than kind.

Hamlet, act 1, scene 2, Hamlet

A man in all the world’s new fashion planted, that hath a mint of phrases in his brain.

William Shakespeare Wikipedia: William Shakespeare  

Love’s Labour’s Lost, act 1, scene 1, Ferdinand

A man loves the meat in his youth that he cannot endure in his age.

A miser grows rich by seeming poor. An extravagant man grows poor by seeming rich.

A peace above all earthly dignities, a still and quiet conscience.

A peace is of the nature of a conquest;
For then both parties nobly are subdued,
And neither party loser.
