Let’s assume you had five minutes to give a speech. You would receive a very large sum of money if you gave a speech that the judges considered “passionate.” You choose the topic, you write the speech. You give a passionate speech, you get the money.
What would you talk about? More importantly, would what you talk about in that speech be what you’re truly passionate about, or would you try to fudge and make people think you were really excited about something you think is “important,” because you think that’s what they want to hear?
