Patience is the state of endurance under difficult circumstances, which can mean persevering in the face of delay or provocation without acting on annoyance/anger in a negative way; or exhibiting forbearance when under strain, especially when faced with longer-term difficulties. Patience is the level of endurance one can take before negativity. It is also used to refer to the character trait of being steadfast.

Patience, that blending of moral courage with physical timidity.

Thomas Hardy, Tess of the d'Urbervilles

Let him that hath no power of patience retire within himself, though even there he will have to put up with himself.

Baltasar Gracián, The Art of Worldy Wisdom, (1647)

Patience makes lighter / What sorrow may not heal. ("sed levius fit patientia quidquid corrigere est nefas")

Horace, Hor. Carm. 1.24

We have only to be patient, to pray, and to do His will, according to our present light and strength, and the growth of the soul will go on. The plant grows in the mist and under clouds as truly as under sunshine; so does the heavenly principle within.

William Ellery Channing letter 2 September 1826

He that will have a cake out of the wheat must tarry the grinding.

William Shakespeare, Troilus and Cressida Act I, scene i

Patience is a nobler motion than any deed.

C.A. Bartol, Radical Problems 1872

Patience is the ballast of the soul, that will keep it from rolling and tumbling in the greatest storms: and he, that will venture out without this to make him sail even and steady will certainly make shipwreck, and drown himself; first, in the cares and sorrows of this world; and, then, in perdition.

Ezekiel Hopkins Death disarmed of it Sting Of Patience under Afflictions

Il n'y a point de chemin trop long à qui marche lentement et sans se presser: il n'y a point d'avantages trop éloignés à qui s'y prépare par la patience.

Translation: There is no road too long to the man who advances deliberately and without undue haste; there are no honours too distant to the man who prepares himself for them with patience.

If the wicked flourish and thou suffer, be not discouraged. They are fatted for destruction; thou art dieted for health.
