I don't know, maybe this is all in my head,  but I feel I can make a conscious decision to switch between an outward energy and an inward energy.

Outward energy feels like I am projecting myself out and looking to interact

Inward energy feels like I am keeping myself to myself and winding down into an inactive state

Just being aware of that seems to allow me to switch between the two

I've been trying it when I haven't felt like talking and suddenly I'm starting a conversation

So I think it's a good awareness to have and experiment with.
