Ruly memorable disasters do not happen by chance. They require a special blend of misunderstanding and misguided effort. Here are three ways to ensure a disaster in your next presentation, and how to avoid them.

Error # 1: belief in magic

Appear with the hope that a coherent, eloquent presentation, useful magically appears once you start talking. Avoid any kind of preparation. Only the wing.

> What happens
Everyone is surprised by the presentation because I expected more. They are also bored and disappointed. It can even be upset that a presentation unprepared public insults for wasting your time. Prepared audio presentations as well, prepared presentations.

> Instead
Prepare. Identify the purpose of your talk. Design a presentation that achieves that goal. Talk with key members of the audience about their expectations. Rehearse.

Error # 2: Memorize your speech

Spend countless hours making every word precious memory so that you can recite it even if he wakes in the middle of the night.

> What happens
Sounds like a machine. And if you stumble on a word that can get stuck - no words. I've seen this happen, and it is painful.

> Instead
Learn from your presentation. Yes, writing a script. Memorize the first practice and last sentences and after making the presentation without looking at the script. The practice often. Over time, you will learn how to convey the key ideas in a natural and normal.

Mistake # 3: talk about yourself

Focusing exclusively on himself. Talk about your background, credentials, and its history. Tell your story. Only talk about yourself. Make the presentation all about you, yourself and your life.

> What happens
They listen politely. If you manage to be entertaining enough, they may actually pay attention. Otherwise, the public reacts thinking, "So what?"

> Instead
Talk about the hearing. I mean, talk about what they need and how they can do.
