People often try to complain to me that their presentation wasn’t how they planned it.
They forgot a point/story/clever thingy, or something.
If you’re doing it well, it should never be exactly how you planned it.
If a presentation is exactly how you planned it, you’re working from a script and aren’t responding to the people in front of you.
This is the Presentations As Classical Music paradigm: presentations are a piece of Mozart (yuh – you should be so lucky) that need rehearsing and rehearsing and rehearsing until you remember the whole ‘script’. You can tell someone from this school as they talk about ‘writing a speech’.
