Many studies show that your audience is going to have a hard time focusing intently for more than 15-20 minutes.

Think about the fact that TED Talks are under 18 minutes long. That's for a reason.

If you take so long to make a point or add so many details, you may be only a third or halfway through your presentation before your audience's attention starts to wander or take a hit.

So think about what you need to cut and what to keep if you only had 20 minutes of undivided attention.

One source on this and other points of presentation deliver is 'Presentation Zen' by Garr Reynolds.

An impactful presentation isn't about fancy transitions, cool visual tricks, or the software you use for your slides.

The most important part is transcending those details and connecting directly with your audience - speaking to them, at their level, and according to their needs to get your point across and make them understand why they should care.
