Failure in Life and Death Situation

I’m having difficulty with some of the suggestions to see failure as a learning tool or to try and court failure at work. I’m a physician and work in the ER where I am dealing with situations where a mistake or “failure” can result in someone’s death. I find it difficult to imagine a situation where I could see this outcome as a learning experience or in any type of positive light. Sometimes the gravity of the outcome makes it difficult for me to feel confident and function effectively.

I’m trying to gain more confidence at work but am having trouble with this piece of it. I appreciate your input. Thanks!
