One of my fave quotes about hope comes from one of my fave movies, 'The Lion in Winter'.
Queen Eleanor & King Henry Plantagenet are having a come-to-Jesus moment in the wine cellar of Chinon castle, & they have the following exchange:
E: There's everything in life but hope.
H: We're both alive... & for all I know, that's what hope is.
The monologue, for anyone who hasn't seen it: https://www.youtube.com/watch?v=QbzcFbhPV-o
