Look, everyone doesn't have to be a dazzling speaker or writer, but we all must put forth effort to up our game when it comes to giving presentations and writing papers.
Here are a few thoughts towards that end:
Read Garr Reynolds' book Presentation Zen. And his blog. Then read them again.
If your presentation is dull, you're doing it wrong. And I mean that in both senses of the word wrong (incorrect & immoral)
To be even clearer: being dull is a sin, a crime, a theft and an assault. Don't waste people's most precious irreplaceable resource - time - with droning messages that don't convey anything useful and that beg to be tuned out.
Prepare. 'Nuff said.
PowerPoint isn't the problem. PowerPoint's defaults are the problem. Reject them with great enthusiasm.
You have my permission to be interesting. You do not have my permission to waste my time.
When giving a presentation, don't be the only guy in the room who doesn't know how much time you have left.
