I would expect the "snowball effect" to be pretty strong, especially for social interactions. Given a day where you tend to seek social interaction vs. a day when you tend to shy away from it, you can get a very different number of (practice) interactions.

There's a lot that can be learned by paying attention to other people and trying to understand what they're thinking. The earlier that someone who's not naturally adept at it realizes that this is important to pay attention to, the earlier they get better at social skills. Some of that can be highlighted for little kids while reading (story) books; paying attention to and asking questions about why the characters do the things in their interactions highlights the idea that other people do things for reasons, and that you can guess what they are (the guessing well is a skill).
