Talk, don't read
Stand, don't sit
Move, don't stand still
Vary the pitch of your voice, don't speak in monotone
Speak loudly, facing the audience, don't mumble facing downward
Make eye contact, don't stare at your laptop
Focus on main points, don't get lost in details
Use outlines, images, and charts, don't have no visual aids
Finish within your time limit, don't run overtime
Summarize your main points at the beginning and end, don't start without an overview and trail off without a conclusion
Notice your audience and respond to its needs, don't ignore audience behavior
Emulate excellent speakers, don't emulate your advisor if they give lousy talks
