Courage Is A Learned Action
- Courage is action in the face of fear, not absence of fear.
- Courage is a learnable set of practices and mindsets, not only innate.
Training Transforms Fear Responses
- British WWII bomb disposal and paratrooper research showed training builds confidence under danger.
- Albert Bandura trained snake-phobic people to hold large snakes, showing fear can be reduced by practice.
