I've been reading a great book about presenting:  Nancy Duarte's HBR Guide to Persuasive Presentations. And it's reinforcing my experience that the key to an effective presentation is not flashy slides--it's a compelling, well-told story.

As Ms. Duarte says: "My best advice is not to start in PowerPoint. Presentation tools force you to think through information linearly, and you really need to start by thinking of the whole instead of the individual lines."

Here are 19 other inspiring quotes to consider next time you need to create a presentation:
