When you're at work, do you ever find yourself fantasizing and being hyper motivated about being home to continue THAT thing you're really excited about or should be doing. But then once you get home all motivation evaporates and you end up doing nothing and feeling guilty about it?
Pretty much every day. I think it's because we have a limited capacity and for many of us our job requires us to mask to some degree and it just takes all of our energy, even if it isn't physically or even intellectually demanding. There's no reason I should feel completely drained and demotivated by just sending emails, but it is what it is.
I try to go somewhere quiet and lay on the floor or something. Or literally touch grass - get feet in the dirt, listen to the wind in the trees, that sort of thing. And stay away from screens for a bit. I'm still trying to find ways to help regulate my nervous system since I need different things on different days but those are some of the most effective for me.
