Sisu

Etymologically, “sisu” (pronounced see’-soo) comes from a Finnish root word that implies “inner” or “inside.” 

In Finnish culture, it’s about adopting the attitude of persistence and determination.

“Sisu is not momentary courage, but the ability to sustain that courage. It is a word that cannot be fully translated. It defines the Finnish people and their character. It stands for the philosophy that what must be done will be done, regardless of cost,” according to Finlandia University.

It’s often described as stoic determination, the tenacity of purpose, grit, and resilience. It’s a form of courage that is presented in situations where success is against the odds.

It’s about persevering your way through challenges.

“It is a compound of bravado and bravery, of ferocity and tenacity, of the ability to keep fighting after most people would have quit, and to fight with the will to win,” The New York Times explained in 1940.

Sisu is doing what’s necessary even when it’s difficult.

Sisu may be a Finnish word, but it’s a universal trait, says Joanna Nylund, author of Sisu: The Finnish Art Of Courage.
