PowerPoint mistakes that drive people crazy
Too many words
Venture capitalist Guy Kawasaki suggests the 10-20-30 rule: Don't use more than 10 slides, don't talk more than 20 minutes, don't use less than 30 point font.
A 30 point font is large. That's good. Less words mean more attention. Otherwise, it's as if you're talking, and your slide is also talking, and the audience is wondering, "Should I listen or read?"
Their solution: daydream.
