How To Make a Good Presentation By Lenon's Version

I'd like to share you about my experience as a student when I do a presentation in front of class. This below the tips:

Prepare and get any presentation materials. Do simple thinking and logic even you can put the thinking in your heart.
Know your audiences .
Practice your speaking on front of mirror and invite someone to listen your presentation.
Make sure the room condition has been set promptly. The note, projector, ballpoint and more are avaiable.
Wear the tidy and polite clothes because your first show is good looking.
Give a smile to audience for a while.
Don't do any weird movement.
Put your both hand like the presenter hand position on the above picture.
Don't ever put your hand on your pocket, scratch your hair, play any ballpoint or another thing weirdly.
Keep thinking about what the benefits will be gotten by audience about your presentation.
Don't ever look an audience only for a long.
Don't ever say you are not already to be a presenter.
Give some jokes if needed (depend on audience condition).
Don't ever story about your privacy that doesn't relate with your presentation.
