Is courage something you have to be born with, or can you develop it?

  In class this unit we talk about courage and type of courage. We use some of people to show courage like Deejai have super physical courage. There a lot more type of courage such as moral courage, physical courage, emotional courage, spiritual courage, social courage and finally intellectual courage.
  This topic I think that is both because you born with lot of courage like want to be brave and want to do lot of thing. However you can developing your courage by the time you get ready such as when you are teenager you are more brave than kid ( developing physical courage), asking more question ( developing intellectual courage) and many more.
  I'm sure that it both because when you born you have little courage but you can develop by the time. What do you think ?
