You're going to get practice where you search out for it, when you're open to and ready for interacting with other people.

I can go to baseball practice, work on my game, and go home when it's over. Or I can ask if someone wants to stay and go for drinks after. Everyone's got the choice of what they want to do. If I love the game but not the people then I'll maybe hang out with a different group instead, or with my partner.

The point behind eliminating these side-effect interactions is that now you can decide when and with whom to interact, rather than being forced into it when you just wanted to get something else done.

Baseball is a team game, so interaction is not a side effect, it's part of the activity.
