There's a moment in writing presentations; you are dispassionately writing and editing point-form notes about the things you want to talk about, a kind of disjoint series of ideas that you know all fit together somehow, and you're really just playing with them to see how they fit, then you take a bit of time off to help someone on IRC and you come back to it.
There, staring you in the face is "the" presentation, hidden among your ridiculously over-detailed notes, trying to push through the mess with a simple, clear, straightforward narrative, something that needs to be said. You can suddenly see the underlying ideas that made the whole set of comments feel necessary, and now you know you need to toss out everything you have... but the message has finally shown up, and thus all is right in the world.
I love that moment.


The next great moment comes when you get everything down to the required time. I did a trial run of my session at work last week. The stopwatch said "25:05" when I pressed stop. Victory!
Although, now I'm busy changing everything around again. And tightening up the graphics on level 3.
