Can anyone help me on my english homework?

so i have english homework and we started on macbeth and i'm asked to write a reflection about "By the end of Act I, scene iii, Macbeth decides not to kill Duncan and to wait for fate to crown him. Consider your belief in “fate”, ”self-fulfilling prophecy” and ” self determination”. Do you think Macbeth would have considered the possibility of becoming king without the Weird Sisters’ prophecies? What does this tell us about his character? Why is it important to establish this early on in the play?" what is a reflection? and how should i write about it:S ?
