My country is only a hundred years old and started as nothing but farmers fighting for independence. We're not just "rich" - we organized ourselves exceptionally efficiently and gained wealth from doing so, even while paying war reparations to Russia and investing massively into the unbelievably generous social safety net we still enjoy today.

Literally any peoples around the Earth can do it, if they really want to.

That feeling of "really want to" is enshrined in the Finnish language as "sisu", "described as stoic determination, tenacity of purpose, grit, bravery, resilience, and hardiness."
