The Sphere of Life Force & Getting Constructively Uncomfortable
Show Notes

The sphere of life force is what I call the space within which we operate before hitting the sisu threshold; our outer boundary of inner strength. Ideally, you want this area to be as wide as possible. This episode describes how to expand it through everyday life and how I use it in daily life and to prepare for challenges during extra long ultra runs.

Show notes:

"Get constructively uncomfortable." - Dr. Rhadi Ferguson, Judo Olympian, BJJ black belt.

Sisu is a reserve of inner strength but it is also a way for us to know ourselves and impact the world in a positive way. Cultivating these reserves of inner strength starts with self-care and continues through self-inquiry. its power then extends to the world through our inspired acts of deep courage and compassion.
