Answer:
courageousness/heart
Step-by-step explanation:
For example, lets say there's a small dog, who's about to fight a larger dog. If the smaller dog isn't scared and believes that it is going to win, then the dog may have a fighting chance in beating the larger dog because the small dog has the willingness and confidence to fight the larger dog.
