Obey the 10-Minute Rule

Neuroscientists have found that the brain gets tired after 10 minutes of any presentation. In other words, no matter how engaging the speaker, audiences will tend to tune out after approximately 10 minutes. A Steve Jobs presentation lasts about 1.5 hours but every 10 to 15 minutes, he breaks up the content with video, demonstrations or guest speakers. He doesn't give his audience time to get bored.
