I don't know if this counts as big or inspiring... But I'm going to post in anyway.
Stoic.
(Plural form , Stoics. Adj form, Stoical)
Definitions.
Somebody impassive: somebody who is unemotional, especially somebody who shows patience and endurance during adversity.
Patient and uncomplaining: showing admirable patience and endurance in the face of adversity without complaining or getting upset.
Short and simple... But, as a HTTYD fan, I find it hillairious.
(Get it? Stoic sounds like Stoick? And Stoick is far from Stoic?)
