You have to be extremely boring. I.E say things like "I like to sit on the beach and look at the sea for hours because it makes me feel like a rock... And I also like to talk about a blade of grass in scientific detail. They fascinate me. I don't like rap music because it makes me fall asleep. I sleep 16 hours a day and have no job."
So good luck to you on being the most boring person in the world!
