Patience

Patience (or forbearing) is the state of endurance under difficult circumstances, which can mean persevering in the face of delay or provocation without acting on negative annoyance/anger; 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. Antonyms include hastiness and impetuousness.
