When presenting an idea you are an expert in, it might be tempting to skip preparing for a presentation and improvise on the spot.
The problem with this approach is, that maybe the most important information you wanted to share comes to mind halfway into your presentation, so you share it in the middle, rather than at the beginning of the talk.
The structure and storytelling of the presentation are lost.
Just because you haven't sat down and worked on a simple outline of your ideas, e.g. a bullet point list.
A plan can help bubble up the most ideas to the top, cross out any lower priority items that don't deserve spending time on them, or rephrase/simplify concepts.
I've been there many times. I still occasionally improvise when presenting ideas, depending on the situation, but whenever given a chance - I prefer to prepare and present in a more structured way.
What's your go-to strategy for preparing for presentations?
