1. Find a purpose outside of yourself.

According to research from psychologist Angela Duckworth , we can endure so much more when we work towards something that contributes to the world beyond ourselves.

To gather firsthand data on sisu for my PhD studies, I completed a 1,500-mile running expedition across New Zealand. I dedicated my run to raising awareness about family violence. Each time I started to feel worn out or was on the verge of giving up, turning to that larger purpose helped me push forward.

When you take on a new challenge or need the strength to continue, find a greater purpose to connect with. It can be your family or friends, or someone who inspires you, or a cause that is close to your heart.
