You could include things that persuade the listener that you are better than everyone else, But be smooth about it. you are not trying to really be the treasurer, you are just giving reasons. Example: I love math, I am good at it, I am responsible, etc. You can drag these out if you need to. Another thing, if you are having a brain fart, write an introduction exlaining who you are(name, age, etc.). I think that's an efficient way to forcibly get started
