People just look better when they smile so you should keep that in mind when you're doing your videos. When people are smiling they come off more friendly and welcoming. This is why you want to smile in your videos.

For some this can be a hard thing to do but you can learn how to do it. First always start your video with a smile and then always make sure to end your video with a smile. Once you have that down you're ready to try to talk while smiling.

The best way to practice this is to grab a clean pen or pencil, put it in your mouth and start to talk. You're going to try to talk the best you can and you'll start to recognize the pitches on your cheeks. Get use to how your face feels when it's in a smiling position.

Once you recognize how your face should feel when it's talking and smiling you can keep that in mind as you're performing to always feel those pitches.
