Things to do just before and during your talk.

Before your talk:

Check your projector. Check the room lights. Find the pointer. Go to the bathroom.

During your talk:

• Show enthusiasm!
• Adopt a comfortable poise.
• Make eye contact with your audience. If possible, look at particular people when making points particularly relevant to them.
• Point slowly and steadily to each element of the slide as you explain them. In figures, point to and explain each axis and each data element. If there are elements that you do not refer to, they should not be in the slide.
• Stop before your time is up.
