Okay, concentrate. Who is the most important person in the world to you?
Or possibly, just an idol of yours. Focus on this idol/celebrity/"person" (meaning it could be basically anyone; such as Lassie, Sponge Bob, Peter Pan, or even Jesus).
Find the most meaningful picture of him/her/it, and describe why this picture perfectly encompasses why you idolize (or just masturbate thinking of) this being.
