How not to present
Do not do any research about who you're presenting to.
Arrive 20 minutes late and ask your audience who they are and what their business is about.
Be arrogant and condescending.
Give limited information and skip the details. Use outdated information and hope no one will notice.
Oversimplify as much as you can. If you don't know an answer, make it up.
Frequently repeat that the audience should buy your product.
Criticize other products.
If someone challenges your arguments, ignore them and move on.

A good reputation is tough to get yet easy to lose. It pays off bringing on board people who will help you maintain it.
