In both your fraternity life and your real life, you will eventually have to speak in public. Always, always, always prepare what you are going to say. You don't have to write it out word for word, but you have to avoid winging it.
You may not realize it, but those listening are judging you when you speak. They aren't doing it consciously. Immediately when you start talking they will say to themselves that 'this guy is sharp' or 'this guy's an idiot'.
This is your opportunity to impress. Don't blow it!
