Read the excerpt from an interview with Florence Griffith-Joyner. WILL: Where does the self-confidence and radiance that you have come from? FLORENCE GRIFFITH-JOYNER: I believe my self-confidence comes from my faith in God and faith that I have in myself, the belief that my parents instilled in me when I was very young that I could do anything that I wanted to do--anything I set my mind to, and anything that I really believed in. With each race, no matter how you do, your self-confidence grows because you're telling yourself, "OK, I've accomplished that whether won or lost. I've learned from that. I'm going to move on." So throughout the years of my entire athletic career I have learned from each race, no matter what. Which theme is supported by this excerpt? Nature teaches important lessons. Self-confidence comes from within. Change is necessary for growth. Self-confidence triumphs over evil.
