Rock warrior's way

Considering the physical demands of climbing, I'm curious what motivated Arno Ilgner to delve into the psychological side of the sport and how he developed these techniques.

The book's philosophical insights about resilience and mindset felt impactful, but I'm wondering if others found these ideas truly applicable to real climbing situations or more abstract.

I wonder if the mental training principles here could be adapted for other risky pursuits or personal challenges beyond climbing, and if readers have tried this.
