Don't start with "My name is". Teaceher HATE that. Trust me. Countless of Honours/AP teachers have told me this. Also be sure to add things nobody knows about you. Like for example you speak 6 languages or something interesting. What makes you, you?
Ex. "I have always been an imaginative person ever since I can remember I have been interested in theatre. When I was a child I would often put on plays for my family and charge them in order to watch it...."
