Every language has untranslatable expressions that are in the cultural core.
In Finland we have one: Sisu.
We are very proud of it, it pulls everyone together and powers up individuals. It makes us unbeatable. We believe that it will save us, magically, always. And it will definitely save Nokia.
The best description that I have read is In Other Words, a book by Christopher Moore. Enjoy!
It is 1939 and two Finnish foot soldiers are pinned down in a battle.
“We are outnumbered,” one soldier says. “There must be over 40 of them, and only two of us.”
“Dear God, it’ll take us all day to bury them!” exclaims the other.
Sisu means a proud refusal to lie down and be beaten.
