The Basics - Create a quiet teaching space with headphones to help drown out any background noises. Ideally your desk will be facing the wall with a fun background. Keep your computer at eye level and if it’s too low - be sure to raise it up with whatever you can find, such as those old cookbooks that you’re never realistically going to use. Lighting should be high and facing you while at the same time eliminate lights coming from underneath or behind you. You have a dull rectangle in which to entertain and educate the world. Bring the energy! Practice with your camera on as you shift, hold up props, visual aides, bring things closer and further away from the camera lens and practice dancing. Lastly, practice using different tones, voices and inflections.
