being brave is being able to overcome a fear. It could be anything for different people. A person could be scared of heights, and they want to overcome it that would be a brave move for them. A wanna be thug could have a fear of standing up to a real thug who takes his money from him so getting a gun and shooting him is the answer. A person might feel brave by winning a street race. It depends on a person's fears.
