Locating a Jordan Peterson quote?

I once saw a video online where Jordan Peterson said that learning new things is harder than it seems like it should be. And as an example he said that whenever you lose a tooth, you often spend the next day sticking your tongue in the hole where your tooth used to be. Because it takes all day for you to get used to the feeling of that tooth not being there anymore.

That s not the exact wording, but it was something like that. Can anyone find the url of that video?
