Presenting where you have to be exactly on the content with no deviation is hard. To do that without sounding like a robot is very hard.

Presenting isn't that hard if you know your content thoroughly, and care about it. You just get up and talk about something that you care about, within a somewhat-structured outline.

Presenting where customers and the financial press are watching and parsing every word, and any slip of the tongue can have real consequences? Yeah, um... find somebody else.
