Answer:
The way I would define courage is being able to do something although you are scared to see the end of it. Many people have to go through things they don't want to do, things that scare them such as going to a work interview, or singing on stage. I think it takes a lot of courage to do those things, because of the fact they are uncomfortable but still proceed to go through with it.
Shorter version:
The way I would define courage is a person being able to do something that they fear would not go in their favor. Having the ability to fight against their fears to continue moving forward to make themselves a better person and to achieve their goal.
Goodluck :)
