I've Been Saying This for a Long Time Now

I think people tend to overestimate how much knowledge they need or like how advanced they need to be in a thing before they can start teaching someone who's just learning it. I was looking for this tweet for Bipadio 11 that mentioned this, but he made the same point. It's very dangerous to wait until you're you've mastered it because your enthusiasm will disappear and you'll forget what it's like to not know it.
