Great idea Balbrae and well produced.
One big suggestion though...
In the audio you are using "I" instead of "you".
I listened to one and automatically my mind starts building a picture of what it thinks you look like talking about how great you are. It's rather amusing.
Imagine seeing a video of someone looking at you saying "I'm great, I'm so amazing" etc
Contrast that to someone looking at you saying "You're great, you're so amazing"
This is pretty important, especially when the voice you hear is different to your own voice.
