Consider the emotional nature of the Apostle Peter. First, have a look at some occasions where he let his emotions run away with him and acted or spoke too hastily: Matthew 16:21-23; Matthew 17:1-5; John 18:1-11. Second, look at how Jesus was able to look beyond these emotional outbursts and see his potential: Matthew 16:17-19. Finally, see how that came true when Peter, under the power of the Holy Spirit, became the spokesperson of the early church: Acts 2:14-41. Nothing in your character is so big that God cannot make something good out of it!
