Sisu Lab
Sisu is an ancient Finnish concept associated with determination and courage in the face of adversity. But sisu is more than perseverance — it is a way of life and a practice of refining one’s character. The Sisu Lab Podcast explores this inner fortitude and its deeply human expression.
Hosted by Elisabet Lahti, the podcast weaves together research, personal experience, and practical insights into human capacity in everyday life. Elisabet has researched sisu since 2012 and completed multiple endurance challenges as part of her ongoing inquiry into the nature of inner strength.

Superordinate Purpose and the Sisu In-Between Our Hearts

Sisu is an interconnected matter. Rarely is your sisu only your sisu or my sisu solely my sisu. One of the main findings of the ultra run field work portion of my PhD on sisu is the idea of sisu that exists, and is born from, the space in-between you and I. This episode is about how we inspire strength and fortitude in each other. Furthermore, our own sisu can be inspired by the strength we see and witness in others and their actions, and this impact can extend to drawing strength from even those dear to us who are long gone. I speak of Viktor Frankl, present Angela Duckworth and James Gross´ concept of superordinate life-goals and propose some journaling work.
Enjoy, brave ones!

Sisu is a Finnish word for a reserve of inner strength, but it’s also a way to positively impact the world. Cultivating this inner fortitude starts with self-inquiry and getting our self-care in order, and from there, extends into courage and community. Its power ultimately reaches into the world through inspired acts of compassion and positive change.
