Re: Developing courage
As David Skaggs said, you have to train with real as possible conditions.
However, those conditions must be appropriate and progressively trained.
It is not about fear, heck we are all afraid, I am. However, you must drill over and over the things or habits you want to be automatic in yourself once the conditions of stress are present in the given situation.
Lots of good advice above.
The answer is train and train some more until it becomes automatic, a habit, and done without thought.
