Finns have a word to describe themselves called “sisu,” which roughly translates to a combination of courage, strength and determination.

Sisu is a Finnish concept and cultural construct that is described through a combination of various English terms including stoic determination, grit, bravery, resilience, and hardiness and is held by Finns themselves to express their national character. It is generally considered to not have a literal equivalent in English.
